[Intel-gfx] [PATCH 0/2] Fixes for selective fetch area calculation

[Jouni Högander]

Currently selective fetch area calculation ends up as bogus area in
following cases:

1. Updated plane is partially or fully outside pipe area
2. Big fb with only part of memory area used for plane

These end up as y1 = 0, y2 = 4 or y2 being outside pipe area. This
patch set addresses these by ensuring update area is within pipe area
and falling back to full update.
