When lemp9 was converted to a variant in CB:64528, the Makefile was not
updated to handle the variant-specific `romstage.c`. This, as would be
expected, caused memory init errors and broke boot on CML-U boards.
Tested lemp9 boots to payload again.

According to the schematics, the components/pins for RTD3 support are
not connected. The enable GPIO for components is tied directly to power
and the reset GPIO is tied to `BUF_PLT_RST#`.

`chipset.cb` is not used when PCH-S is selected, as is the case for
RPL-HX. Fix setting power limits by putting the definitions in the
correct file.

Multiple users have requested to have the sysfs value `product_uuid` be
filled, and at least one wants DMI to report the serial number. Add the
drivers so that we can fill them in when flashing firmware.

System76 EC sets PL4 values through PECI based on AC state [1]. Remove
the static PL4 values from coreboot since they won't be used. This will
result in sysfs reporting the package default for PL4.
