Current code only cares whether the PCH is LP or not. However, MRC wants
to differentiate between desktop and non-LP mobile platforms as well. As
the PCH is soldered onto the mainboard, add a facility to retrieve which
platform coreboot is running on by checking the PCH's LPC device ID. The
only user of the `pch_silicon_type` function is the `pch_is_lp` function
so replace the former with the new `get_pch_platform_type` function. The
function needs to be defined in both romstage and ramstage where PCI ops
have different signatures, hence the two copies.

Knowing this, it is possible to compute the MRC slot population masks
