Drop the old, redundant code for mirroring LPC registers to DMI and make
use of the new common code.
Select the new Kconfig option for LPC DMI mirroring by the option
SOC_INTEL_COMMON_PCH_BASE, which is selected by platforms starting with
SPT, except APL and Xeon-SP. For Xeon-SP, select DMI and the new Kconfig
directly.
APL, even though it's younger than SPT, does not need mirroring.
Test: Set LGMR address by calling `lpc_open_mmio_window` and check that
both the PCI cfg and DMI LGMR register get written correctly.
Tested successfully on clevo/cml-u.

The code for setting the LPC generic memory range uses an array of fixed
address ranges not needing explicit decoding, to decide if the address
needs to be written to the LGMR register. Most platforms only mistakenly
add the PCH reserved mmio range, that is not decoded generally,
effectively breaking the mechanism. Only APL uses the array correctly.
That code, in it's current state, does not work (except for APL) and
currently, there is not a single user. Thus, drop it before people start
using it.

This change drops the parameter `struct device *dev` from the function
`soc_get_gen_io_dec_range()`. This function uses the parameter dev to
get a pointer to config structure for extracting the decode ranges
configured by mainboard in device tree. However, there is no separate
chip driver for the LPC device which means that the SoC code can use
`config_of_soc()` to get to SoC chip config instead of using the LPC
device.
This change is being done in preparation to clean up the device
tree/chip config access in early stages that allows for optimizing
the inclusion of device tree elements in the early stages.

They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
copyright holder?
- People sometimes have their editor auto-add themselves to files even
though they only deleted stuff
- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?
Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

We had two ways to configure the serial IRQ mode. One time in the
devicetree for FSP and one time through Kconfig for coreboot. We'll
use `enum serirq_mode` from soc/intel/common/ as a devicetree option
instead. As the default is `quiet mode` here and that is the most
common mode, this saves us a lot of lines.
In four cases kblrvp8, 11 and librem 13v2, 15v3, we had conflicting
settings in devicetree and Kconfig. We'll maintain the `continuous`
selection, although it might be that coreboot overrode this earlier
on the kblrvps.
Note: A lot of Google boards have serial IRQ enabled, while the pin
seems to be unconnected?
