[Intel-gfx] [PATCH 2/3] drm/i915/display: Use original src in psr2 sel fetch area calculation

["Jouni Högander" <jouni.hogander@intel.com>]

drm_plane_state->src is modified when offset is calculated:

before calculation:
src.x1 = 8192, src.y1 = 8192

after calculation (pitch = 65536, cpp = 4, alignment = 262144)
src.x1 = 8192, src.y1 = 0, offset = 0x20000000

Damage clips are relative to original coodrdinates provided by
user-space. To compare these against src coordinates we need to use
original coordinates as provided by user-space. These can be obtained
by using drm_plane_state_src.
