Merge branch 'pm-cpuidle'
- Avoid using deep idle states during initialization in the intel_idle
driver to work around device handling issues (Rafael Wysocki)
- Fix and refactor the ACPI processor driver code related to ACPI _LPI
support and add ACPI _LPI support to intel_idle based on that ACPI
processor driver update (Rafael Wysocki)

ACPI: processor: idle: Add switch for strict _LPI processing
ACPI: processor: idle: Relocate acpi_processor_extract_lpi_info()
ACPI: processor: idle: Introduce acpi_processor_extract_lpi_info()
ACPI: processor: idle: Introduce too_many_states() for _LPI
ACPI: processor: idle: Rework flatten_lpi_states()
ACPI: processor: idle: Rearrange loop in acpi_processor_get_lpi_info()
ACPI: processor: idle: Drop redundant _LPI presence checks
ACPI: processor: idle: Rework first-level _LPI states processing
ACPI: processor: idle: Rearrange acpi_processor_get_lpi_info()
