platform/x86:intel/pmc: Call pmc_get_low_power_modes from platform init
In order to setup a table of low power mode requirements for Meteor Lake,
pmc_core_get_low_power_modes() will need to be run from platform init code
so that the enabled modes are known, allowing the use of the
pmc_for_each_mode helper. Make the function global and call it from the
platform init code.
