Current the common soc code automatically selects PCIEXP_CLK_PM and
PCIEXP_L1_SUB_STATE which breaks booting Windows with a PCIE NVIDIA
graphics card attached on mainboards that do not have a CLKREQ# signal.
This is commonly used on server and workstations boards where the
additional power savings of L1 substate are not required.
Make the PCIEXP_CLK_PM and PCIEXP_L1_SUB_STATE default y but do not
select it anymore by the soc code, thus we can disable it in the
mainboard code.

On ChromeOS systems with a serial-enabled BIOS and vboot writing a new
firmware image to the Chrome EC, it was possible for the TCO watchdog
timer to trip 2 times before tco_configure() was called in romstage.
This caused an extra reboot of the system (at a rather inopportune time)
and because the EC didn't perform a full reset, the system boots into
recovery mode.
This patch moves the call to tco_configure() for Tiger Lake from
romstage to bootblock, in order to make sure the TCO watchdog timer is
halted before vboot_sync_ec() runs in romstage. It should be harmless to
configure the TCO device earlier in the boot flow.

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.
