soc/intel: Enable TME based on supported CPU SKU and config option
This patch removes the static kconfig being used to fill in TME enable
FSP UPD. Instead use`is_tme_supported()` and `CONFIG(INTEL_TME)` to check
if the CPU has required TME support rather than hardcoding.
TEST=FSP debug log shows `TmeEnable` UPD is set appropriately for the
TME-supported CPU SKUs.
As per FSP-M debug log:
Without this CL, Alder Lake-P CPU SKU without TME support:
[SPEW ] TmeEnable = 0x1
With this CL, Alder Lake-P CPU SKU without TME support:
[SPEW ] TmeEnable = 0x0
