Pull ACPI fixes from Rafael Wysocki:
 "They fix an ACPI thermal management regression introduced by a recent
  FADT handling cleanup, an ACPI tools build issue introduced by a
  recent ACPICA commit and a PCC mailbox initialization bug causing
  lockdep to complain loudly.

  Specifics:

   - Revert a recent ACPICA cleanup that attempted to get rid of all
     FADT version 2 legacy, but broke ACPI thermal management on at
     least one system (Rafael Wysocki).

   - Fix cross-compiled builds of ACPI tools that stopped working after
     a recent cleanup related to the handling of header files in ACPICA
     (Lv Zheng).

   - Fix a locking issue in the PCC channel initialization code that
     invokes devm_request_irq() under a spinlock (among other things)
     and causes lockdep to complain (Hoan Tran)"
