soc/intel/tigerlake: Run pmc_set_acpi_mode() during .init in pmc_ops 

pmc_set_acpi_mode() should run after Chrome EC dealt with all host event
bits, like SMI mask (otherwise the FAFT firmware_FWScreenCloseLid test
will fail).

BUG=b:153249055
TEST=FW_NAME=malefor emerge-volteer coreboot chromeos-bootimage
Change the GBB flag to 0x140 then check SMI mask during depthcharge
phase, make sure it's 0x0000000000000001.
