Merge branches 'acpi-apei', 'acpi-prm' and 'acpi-docs'

Merge APEI, PRM and documentation udpates for 5.16-rc1:

 - Mark apei_hest_parse() static (Christoph Hellwig).

 - Relax platform response timeout to 1 second after instructing it
   to inject an error (Shuai Xue).

 - Make the PRM code handle memory allocation and remapping failures
   more gracefully and drop some unnecessary blank lines from that
   code (Aubrey Li).

 - Fix spelling mistake in the ACPI documentation (Colin Ian King).
