Only scan one device if it's a PCIe downstream port.
A PCIe downstream port normally leads to a link with only device 0 on
it. As an optimization, scan only for device 0 in that case.

List of changes:
1. Create Module Type macros as per Memory Type
(i.e. DDR2/DDR3/DDR4/DDR5/LPDDR4/LPDDR5) and fix compilation
issue due to renaming of existing macros due to scoping the Memory
Type.
2. Use dedicated Memory Type and Module type for `Form Factor`
and `TypeDetail` conversion using `get_spd_info()` function.
3. Create a new API (convert_form_factor_to_module_type()) for
`Form Factor` to 'Module type' conversion as per `Memory Type`.
4. Add new argument as `Memory Type` to
smbios_form_factor_to_spd_mod_type() so that it can internally
call convert_form_factor_to_module_type() for `Module Type`
conversion.
5. Update `test_smbios_form_factor_to_spd_mod_type()` to
accommodate different memory types.
6. Skip fixed module type to form factor conversion using DDR2 SPD4
specification (inside dimm_info_fill()).
Refer to datasheet SPD4.1.2.M-1 for LPDDRx and SPD4.1.2.L-3 for DDRx.

This patch changes the sc7180 boards to use the new common MIPI panel
framework, which allows more flexible initialization command packing and
sharing panel definitions between boards. (I'm taking the lane count
control back out again for now, since it seems we only ever want 4 for
now anyway, and if we ever have a need for a different lane count it's
not clear whether that should be a property of the board or the panel or
both. Better to leave that decision until we have a real use case.)
Also, the code was not written to deal with DCS commands that were not a
length divisible by 4 (it would read over the end of the command
buffer). The corresponding kernel driver seems to pad the command with
0xff instead, let's do the same here. (Also increase the maximum allowed
command length to 256 bytes, as per Qualcomm's recommendation.)

All boards that are trying to use MIPI panels eventually run into the
problem that they need to store physical parameters and a list of DCS
initialization commands for each panel, and these commands can be very
different (e.g. a large amount of very short commands, a few very large
commands, etc.). Finding a data format to fit all these different cases
efficiently into the same structures keeps being a challenge, and the
Kukui mainboard already once put a lot of effort into designing a
clean, flexible and efficient solution for this. This patch moves that
framework into a common src/device/mipi/ library where it can be used by
other boards as well. (Also, this will hopefully allow us to save some
duplicated work when using the same panel on different boards at some
point.)

With the introduction of fw_config support in coreboot, it is possible
for mainboards to control the state of a device (on/off) in ramstage
using fw_config probe conditions. However, the device tree in
immutable in all other stages and hence `is_dev_enabled()` does not
really reflect the true state as in ramstage.
This change adds a call to `fw_config_probe_dev()` in
`is_dev_enabled()` when device tree is immutable (by checking
DEVTREE_EARLY) to first check if device is disabled because of device
probe conditions. If so, then it reports device as being
disabled. Else, dev->enabled is used to report the device state.
This allows early stages (bootblock, romstage) to use
`is_dev_enabled()` to get the true state of the device by taking probe
conditions into account and eliminates the need for each caller to
perform their own separate probing.
