HV: CAT: add platform specified info for CLOS

IF CAT is supported, and we want setup initial values to
IA32_Type_MASK_n MSRs, We can define a global structure
platform_clos_array[PLATFORM_CLOS_NUM], it has 2 members:

1.msr_index, the MSR address of IA32_Type_MASK_n
2.clos_masky, the initial valuses

Global varible platform_clos_num is the number of  IA32_Type_MASK_n,
from IA32_Type_MASK_0 to IA32_Type_MASK_<CLOS_MAX_NUM - 1>
