Merge branches 'acpi-pm' and 'acpi-properties'

Merge an ACPI power management quirk and a change related to the
handling of ACPI device properties for 6.4-rc1:

 - Do not turn off unused power resources during initialization on the
   Toshiba Click Mini (Hans de Goede).

 - Support strings in device properties supplied by ACPI _DSM on Apple
   platforms (Hector Martin).

* acpi-pm:
  ACPI: PM: Do not turn of unused power resources on the Toshiba Click Mini

* acpi-properties:
  ACPI: property: Support strings in Apple _DSM props
