soc/intel/common: Make read_pmc_lpm_requirements more clear
Commit 2eb100dd12 added PMC LPM requirements to the the PEP ACPI
objects, but it was not made clear that one of the pointer arguments to
the mentioned function is not supposed to be NULL and Coverity
complained. Make the intention clear by instead asserting that `info`
cannot be NULL.
Fixes: Coverity CID 1462119
