[PATCH 3/3] IntelSiliconPkg: Add IgdOpRegion30.h to support IGD OpRegion v3.0


Digant H Solanki
 

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3426

- There are many OpRegion fields obsoleted in MBOX1
- MBOX2 is re-purposed for Backlight related fields for dual LFP.
- Backlight related fields moved to MBOX2 from MBOX3
and some fields are obsoleted in MBOX3.

Digant,
The notation "PATCH 3/3" indicates part 3 of a 3 patch series.
However since this is a single patch, the subject line could simply indicate [PATCH v3]. Something to consider for future reviews.

Thanks,
Sai

- There are many OpRegion fields obsoleted in MBOX1
- MBOX2 is re-purposed for Backlight related fields for dual LFP.
- Backlight related fields moved to MBOX2 from MBOX3 and some fields are obsoleted in MBOX3.
