[PATCH RESEND 5.15.y 0/3] Use access_width for _CPC package when provided by the platform firmware

[Easwar Hariharan <eahariha@xxxxxxxxxxxxxxxxxxx>]

This series backports the original patch[1] and fixes to it[2][3], all marked for
stable, that fix a kernel panic when using the wrong access size when
platform firmware provides the access size to use for the _CPC ACPI
package.

This series was originally sent in response to an automated email
notifying authors, reviewers, and maintainer of a failure to apply patch
[3] to linux-5.15.y at [4].
