intel_pstate: Add X86_FEATURE_APERFMPERF to cpu match parameters.

KVM environments do not support APERF/MPERF MSRs. intel_pstate cannot
operate without these registers.

The previous validity checks in intel_pstate_msrs_not_valid() are
insufficent in nested KVMs.

ACPI / Battery: Add a _BIX quirk for NEC LZ750/LS

The AML method _BIX of NEC LZ750/LS returns a broken package which
skips the first member "Revision" (ACPI 5.0, Table 10-234).

Add a quirk for this machine to skip member "Revision" during parsing
the package returned by _BIX.

Revert "intel_idle: mark states tables with __initdata tag"

This reverts commit 9d046ccb98085f1d437585f84748c783a04ba240.

Commit 9d046ccb98085 marks all state tables with __initdata, but
the state table may be accessed when doing CPU online, which then
causing system crash as below:
