soc/intel/common/block: Manage power state variable from common PMC block
This patch helps managing power state variables from within the
library. Adds migrate_power_state which migrates the chipset
power state variable, reads global power variable and adds it
in cbmem for future use. This also adds get_soc_power_state_values
function which returns the power state variable from cbmem or
global power state variable if cbmem is not populated yet.
