drm/i915/gmbus: Add Wa_16025573575 for PTL/WCL for bit-bashing
As per Wa_16025573575 for PTL/WCL, set the GPIO masks bit before starting
bit-bashing and maintain value through the bit-bashing sequence. After the
bit-bashing sequence is done, clear the GPIO masks bits.
v2:
-Use new helper for display workarounds. (Jani)
-Use a separate if-block for the workaround. (Gustavo)
v3:
-Document the workaround details in intel_display_wa.c
-Extend the workaround to WCL too. (Gustavo)
v4:
-Fix the platform check. (Gustavo)
-Avoid read when preserve bits are 0. (Gustavo)
