[SRU][JAMMY][PULL][IOTG][RPL] Enable TGPIO support on Intel Raptor lake

[Philip Cox]

BugLink: https://bugs.launchpad.net/bugs/2018282

SRU Justification:

[Impact]
Adding support for TGPIO for Intel Raptor Lake platform

[Fix]
This is a series of patches to add support for TGPIO for the Intel
Raptor Lake platform


[Test Plan]
I've performed some testing Raptor Lake, and the QA team, and Intel
will be performing more thorough testing once a kernel with this
support is available in an IOTG image.

[Where problems could occur]
This is a backport from a 5.19 kernel. Most of the patches had some
minor context changes, but there were no major changes required. There
is a chance that the behaviour has changed for previous platforms and
the existing functionality is altered. I believe this is not likely, as
most of the patches seem to be extending functionality, rather than
changing the flow of existing code for the most part.
