Merge branches 'acpi-processor', 'acpi-cppc', 'acpi-apei' and 'acpi-sleep' 

* acpi-processor:
  ACPI: enable ACPI_PROCESSOR_IDLE on ARM64
  arm64: add support for ACPI Low Power Idle(LPI)
  drivers: firmware: psci: initialise idle states using ACPI LPI
  cpuidle: introduce CPU_PM_CPU_IDLE_ENTER macro for ARM{32, 64}
  arm64: cpuidle: drop __init section marker to arm_cpuidle_init
  ACPI / processor_idle: Add support for Low Power Idle(LPI) states
  ACPI / processor_idle: introduce ACPI_PROCESSOR_CSTATE

* acpi-cppc:
  mailbox: pcc: Add PCC request and free channel declarations
  ACPI / CPPC: Prevent cpc_desc_ptr points to the invalid data
  ACPI: CPPC: Return error if _CPC is invalid on a CPU

* acpi-apei:
  ACPI / APEI: Add Boot Error Record Table (BERT) support
  ACPI / einj: Make error paths more talkative
  ACPI / einj: Convert EINJ_PFX to proper pr_fmt

* acpi-sleep:
  ACPI: Execute _PTS before system reboot
