Merge branch 'acpi-driver'

Merge updates of drivers handling devices defined in the ACPI
specification and other generic devices with ACPI interfaces for
6.20-rc1/7.0-rc1:

 - Add a piece of documentation explaining why binding drivers directly
   to ACPI device objects is not a good idea in general and why it is
   desirable to convert drivers doing so into proper platform drivers
   that use struct platform_driver for device binding (Rafael Wysocki)

 - Convert multiple "core ACPI" drivers, including the NFIT ACPI device
   driver, the generic ACPI button drivers, the generic ACPI thermal
   zone driver, the ACPI hardware event device (HED) driver, the ACPI EC
   driver, the ACPI SMBUS HC driver, the ACPI Smart Battery Subsystem
   (SBS) driver, and the ACPI backlight (video) driver to proper platform
   drivers that use struct platform_driver for device binding (Rafael
   Wysocki)

 - Use acpi_get_local_u64_address() in the ACPI backlight (video) driver
   to evaluate _ADR instead of evaluating that object directly (Andy
   Shevchenko)
