Sukumar Ghorai ed1c03a138 soc/intel: separate slp-s0 residency counter frequency in LPIT table 
Intel platforms use Low Power Idle Table (LPIT) to enumerate platform
Low Power Idle states. There are two types of low power residencies
 a) CPU PKG C10 - read via MSR (Function fixed hardware interface)
 b) Platform Controller Hub (PCH) SLP_S0 - read via memory mapped IO

Ref. https://www.uefi.org/sites/default/files/resources/Intel_ACPI_Low_Power_S0_Idle.pdf,
section 2.2.1: value of 0 indicates that counter runs at TSC frequency.

Ref. Intel 64 and IA-32 Architectures Software Developer’s Manual (Vol 4)
MSR 0x632: PC10 residency counter is at same frequency as the TSC.
Whereas slp_s0 residency counter running in different frequency.
