4. Add new MSR 0xc85 IA32_YMM
4.
a. Update eNEM init flow:

- Set MSR 0x1891 IA32_CR_SF_QOS_MASK_1 = no. of ways of LLC - (2^(no. of data ways)-1)
- Set MSR 0x1892 IA32_CR_SF_QOS_MASK_2 = (2^(no. of data ways)-1)
- Set MSR 0xC85 L3_Protected_ways = (2^(no. of data ways)-1)

b. Update eNEM teardown flow:
- Set MSR 0xC85 L3_Protected_ways = 0x00000
