Merge branch 'acpi-enumeration'
* acpi-enumeration:
ACPI: remove unnecessary INIT_LIST_HEAD
ACPI / platform: include missed header into acpi_platform.c
platform / ACPI: Attach/detach ACPI PM during probe/remove/shutdown
mmc: sdhci-acpi: add SDHCI ACPI driver
ACPI: add SDHCI to ACPI platform devices
ACPI / PNP: skip ACPI device nodes associated with physical nodes already
i2c / ACPI: add ACPI enumeration support
ACPI / platform: Initialize ACPI handles of platform devices in advance
ACPI / driver core: Introduce struct acpi_dev_node and related macros
ACPI: Allow ACPI handles of devices to be initialized in advance
ACPI / resources: Use AE_CTRL_TERMINATE to terminate resources walks
ACPI: Centralized processing of ACPI device resources
ACPI / platform: Use common ACPI device resource parsing routines
ACPI: Move device resources interpretation code from PNP to ACPI core
ACPI / platform: use ACPI device name instead of _HID._UID
ACPI: Add support for platform bus type
ACPI / ia64: Export acpi_[un]register_gsi()
ACPI / x86: Export acpi_[un]register_gsi()
ACPI: Provide generic functions for matching ACPI device nodes
driver core / ACPI: Move ACPI support to core device and driver types
