Split `i2c.h` into three pieces to ease reuse of the generic defi-
nitions. No code is changed.
* `i2c.h` - keeps the generic definitions
* `i2c_simple.h` - holds the current, limited to one controller driver
per board, devicetree independent I2C interface
* `i2c_bus.h` - will become the devicetree compatible interface for
native I2C (e.g. non-SMBus) controllers

Move the FSP-specific call for tearing down cache-as-RAM out of
postcar.c and replace it with an empty weak function.
This patch omits checking if (IS_ENABLED(CONFIG_FSP_CAR)). The
temp_ram_exit.c file with the real fsp_temp_ram_exit() is only built
when CONFIG_FSP_CAR is true.

Our current struct for I2C segments `i2c_seg` was close to being compa-
tible to the Linux version `i2c_msg`, close to being compatible to SMBus
and close to being readable (e.g. what was `chip` supposed to mean?) but
turned out to be hard to fix.
Instead of extending it in a backwards compatible way (and not touching
current controller drivers), replace it with a Linux source compatible
`struct i2c_msg` and patch all the drivers and users with Coccinelle.
The new `struct i2c_msg` should ease porting drivers from Linux and help
to write SMBus compatible controller drivers.
Beside integer type changes, the field `read` is replaced with a generic
field `flags` and `chip` is renamed to `slave`.
Patched with Coccinelle using the clumsy spatch below and some manual
changes:
* Nested struct initializers and one field access skipped by Coccinelle.
* Removed assumption in the code that I2C_M_RD is 1.
* In `i2c.h`, changed all occurences of `chip` to `slave`.

Get rid of old hybrid graphics driver and use the new one.
1. Disable IGD and PEG in early romstage.
The PEG port will get disabled on devices that do not have a
discrete GPU. The power savings are around ~1Watt.
The disabled IGD does no longer waste GFX stolen memory.
2. Get rid of PCI driver
The Nvidia GPU can be handled by the generic PCI driver and allows
to use the ACPI _ROM generator for Switchable graphics.
3. Settings are stored in devicetree.
One driver for all Lenovo hybrid graphics capable devices.
4. Add support for Thinker1 GPU power handling.
Only boards that do use reference design 2012 are known to be
supported. Needs test on boards that do you use reference design 2013.
Should reduce idle power consumption when using IGD by ~5Watt.
Tested on Lenovo T430 without DGPU. PEG port is disabled.
Needs test on all devices.

Introduce a chip_driver that uses devicetree instead of Kconfig.
The new driver has the following advantages:
* No more wasted IGD GFX stolen memory
* Can be used by T500 series
* Is even run on devices that do not have a dGPU installed
* Can disable unused PEG port on devices without dGPU (and save power)
* Use devicetree instead of Kconfig options
* Support for multiple hybrid GPIO active levels
* Support for backlight control GPIO
* Support for _ROM on Optimus capable devices
The driver is split into romstage part and ramstage part.
Every mainboard has to call the driver in romstage to get the requested
GPU state. The mainboard code then has to toggle GPU power or disable
the IGD or PEG port.
The ramstage part does handle the hygrid graphics GPIO, including
optional backlight mux GPIO. Every GPIO can have it's own active level,
as defined in devicetree. Devices are no longer disabled in ramstage.
The existing hybrid graphics driver does the same configuration and
should not interfere with this commit until it has been removed.

The function find_fsp() parses the FSP header and returns either a valid
pointer to the FSP_INFO_HEADER or an error code. The caller of
find_fsp() only takes care about a NULL-pointer but not about a possible
error code. This leads to memory access violations in case of error when
FspTempRamInit is called.
To avoid this and to let the user know that there was an error while
parsing the FSP header show an error message and the error code.

The macro FPGA_SET_PARAM was introduced to make the setting of different
FPGA registers with the appropriate values from hwinfo more
transparent. The hwilib takes care about the size of the provided buffer
where the requested value should be stored in. The fields in hwinfo have
not always the same size as the matching registers in the FPGA. So to
avoid errors resulting in a too small buffer when calling hwilib_get_field()
the buffer is now fixed to 32 bit and will be casted to the destination
type when the value is written into the FPGA register.
Changing the field size in hwilib would be the wrong way as the defined
lengths are specified this way to be expandable in the future.
In addition the number of maximum supported temperature sensors is
increased to 8 as the FPGA now supports more.

According to the datasheet the RTC needs a power rising slope of no more
than 100µs/V to ensure a correct power-on reset. If the mainboard that
hosts the RTC cannot guarantee this, a software reset sequence is needed
in the case where the battery was drained completely.
As the rising slope of the power supply depends on so many parameters
and is highly mainboard specific, refactor the initialization code to
perform a software reset every time a power loss event is recognized by
the RTC.
