We shouldn't attempt to read EDID in atomic_check. We really shouldn't

The below commit
"drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2"
introduces a slight behavioral change to rmfb. Instead of disabling a crtc
when the primary plane is disabled, it now preserves it.
Since DC is currently not equipped to handle this we need to fail such
a commit, otherwise we might see a corrupted screen.
This is based on Shirish's previous approach but avoids adding all
planes to the new atomic state which leads to a full update in DC for
any commit, and is not what we intend.
Theoretically DM should be able to deal with states with fully populated planes,
even for simple updates, such as cursor updates. This should still be
addressed in the future.

The order of planes is given by the order they are enumerated
by kms.
Planes with a higher ID appears above planes with a lower ID.
Currently the planes are enumerated in the wrong order,
putting the nv12 only plane after the two RGBA planes.
This patch corrects the plane enumeration order such that all
the overlay planes are initialized first then the primary planes.
Due to this change in order the dc_add_plane_to_context() shall
receive the planes in reverse order hence this patch reverses
the parsing of planes in DM side itself.

The drm layer expects aux->transfer() to return the payload bytes read.
Currently dm_dp_aux_transfer() returns the payload size which does not
gets updated during the read, hence not giving the right data for the
drm layer to pars edid. This leads to the drm layer to conclude as the
edid is BAD and hence some monitors/devices dont get detected properly.

bytes read during DP_AUX_NATIVE_READ & DP_AUX_I2C_READ.
