[GIT PULL] ACPI IORT changes for v4.12

[Lorenzo Pieralisi]

Hi Catalin, Will,

I have collected the following ACPI/IORT patches for the 4.12 release:

- IORT interface minor clean-ups
- IORT platform devices (IORT named components) devid mapping interface
  implementation
- ACPI core changes to enable platform MSIs

ACPI core changes have been acknowledged by the ACPI maintainer and
I reviewed/updated the IORT patches.

This pull request provides the groundwork to implement platform MSIs
in ACPI for ARM64, the irqchip changes enabling GIC ITS platform
MSIs will be merged via the irqchip tree.

Please consider pulling it.

Thanks !
Lorenzo

  ACPI: platform: setup MSI domain for ACPI based platform device (2017-03-30 10:20:01 +0100)

----------------------------------------------------------------
ACPI ARM64 specific changes for v4.12.

Patches contain:

- IORT kernel interface misc clean-ups
- IORT id mapping interface refactoring in preparation for platform
  MSI (IORT named components -> GIC ITS mappings) devid mapping code
- IORT id mapping implementation for named components nodes to ITS nodes,
  in order to provide the kernel with a firmware interface to map
  platform devices devids to GIC ITS components
