Merge branches 'acpi-cppc' and 'acpi-tables'

Merge ACPI CPPC library fixes and an ACPI MRRM table parser fix for
6.18-rc6.

* acpi-cppc:
ACPI: CPPC: Limit perf ctrs in PCC check only to online CPUs
ACPI: CPPC: Perform fast check switch only for online CPUs
ACPI: CPPC: Check _CPC validity for only the online CPUs
ACPI: CPPC: Detect preferred core availability on online CPUs

* acpi-tables:
ACPI: MRRM: Fix memory leaks and improve error handling
