[PATCH 0/2] Introduce helper for display workarounds and add Wa_16025573575

[Ankit Nautiyal]

This series introduces a generic infrastructure for querying display
workarounds. The goal is to simplify WA checks, avoid open-coded conditions,
and make it easier to extend support for future workarounds.

Patch 1 introduces the base infrastructure using an enum and a central
helper function. It also migrates Wa_16023588340 to use this new interface.

Patch 2 adds support for Wa_16025573575, which applies to PTL platforms
and requires preserving additional GPIO bits in GMBUS.

The series is in response to the suggestions to unify workaround handling
and allowing future automation or generation of WA logic in [1].
