Merge branches 'acpi-properties', 'acpi-tables', 'acpi-x86' and 'acpi-soc' 

Merge changes related to ACPI data-only tables handling and ACPI device
properties management, x86-specific ACPI code changes and ACPI SoC driver
changes for 6.1-rc1:

 - Clean up the ACPI LPSS (Intel SoC) driver (Andy Shevchenko).

 - Add a quirk for Dell Inspiron 14 2-in-1 for StorageD3Enable (Mario
   Limonciello).

 - Drop unused dev_fmt() and redundant 'HMAT' prefix from the HMAT
  parsing code (Liu Shixin).

 - Make ACPI FPDT parsing code avoid calling acpi_os_map_memory() on
   invalid physical addresses (Hans de Goede).

 - Silence missing-declarations warning related to Apple device
   properties management (Lukas Wunner).

* acpi-properties:
  ACPI: property: Silence missing-declarations warning in apple.c

* acpi-tables:
  ACPI: HMAT: Drop unused dev_fmt() and redundant 'HMAT' prefix
  ACPI: tables: FPDT: Don't call acpi_os_map_memory() on invalid phys address

* acpi-x86:
  ACPI: x86: Add a quirk for Dell Inspiron 14 2-in-1 for StorageD3Enable

* acpi-soc:
  ACPI: LPSS: Deduplicate skipping device in acpi_lpss_create_device()
  ACPI: LPSS: Replace loop with first entry retrieval
