soc/intel/skylake: Prevent disabling of TCO
In Skylake/Kabylake, if ACPI PM timer is disabled then TCO also gets
disabled & vice versa.
FSP default config for EnableTcoTimer is disabled, this caused ACPI PM
timer & TCO to be disabled by FSP even when config PmTimerDisable = 0.
Thus update FSPS UPD EnableTcoTimer in accordance to devicetree config
PmTimerDisable.
BUG=None
TEST= Build for Soraka with PmTimerDisable=0 & check if TCO caused
reboot after running shell command: cat >> /dev/watchdog0
