soc/intel/common/block/cpu: Introduce CAR_HAS_L3_PROTECTED_WAYS Kconfig
Alder Lake onwards IA SoC to select CAR_HAS_L3_PROTECTED_WAYS from SoC
Kconfig and here is modified flow as below:
Add new MSR 0xc85 IA32_L3_PROTECTED_WAYS
Update eNEM init flow:
- Set MSR 0xC85 L3_Protected_ways = (1 << data ways) - 1
Update eNEM teardown flow:
- Set MSR 0xC85 L3_Protected_ways = 0x00000
BUG=b:168820083
TEST=Verified filling up the entire cache with memcpy at the beginning
itself and then running the entire bootblock, verstage, debug FSP-M
without running into any issue. This proves that code caching and
eviction is working as expected in eNEM mode.
