mb/google/brya/brya0: Manually probe fw_config for DB_LTE
In order to use the USB WWAN module in USB mode (as opposed to PCIe),
the PCIe RP must be turned off at the FSP level. The `probe` statement
in the devicetree unfortunately takes effect too late, because the UPDs
for disabling/enabling PCIE RP belong to FSP-M (romstage), whereas
fw_config probing for devicetree is done in ramstage.
Add a new variant-specific file which will handle manually setting the
UPD based on FW_CONFIG instead.
BUG=b:180166408
TEST=set CBI FW_CONFIG field to LTE_USB, see message in console,
set field to LTE_PCIE, do not see message in console.
