x86/mm: Don't disable PCID when INVLPG has been fixed by microcode
commit f24f669d03f884a6ef95cca84317d0f329e93961 upstream.
Per the "Processor Specification Update" documentations referred by
the intel-microcode-20240312 release note, this microcode release has
fixed the issue for all affected models.
So don't disable PCID if the microcode is new enough. The precise
minimum microcode revision fixing the issue was provided by Pawan
Intel.
