x86/apic: Update TSC_DEADLINE quirk with additional SKX stepping

Browse source

SKX stepping-3 fixed the TSC_DEADLINE issue in a different ucode
version number than stepping-4.  Linux needs to know this stepping-3
specific version number to also enable the TSC_DEADLINE on stepping-3.

The steppings and ucode versions are documented in the SKX BIOS update:
