[PATCH i-g-t 2/2] igt/kms_rotation_crc: Add RGB565 90 degree test for gen>9

[Juha-Pekka Heikkila]

Gen10 onwards 90 and 270 degree rotations are supported for RGB565 format.

v2 (Ville Syrjälä):
As a side effect to keep bad-pixel-format test valid on all supported
platforms it need to use DRM_FORMAT_C8 now.

While at it clean up kms_rotation_crc test a bit, take out
test_plane_rotation_ytiled_obj() function as
test_plane_rotation() can basically do the same.

What I've been thinking for pixel formats not supported by cairo is that
we'd add software routines to convert between them and XRGB8888 and hook
that up so that we do the conversion to/from XRGB888 in the cairo
surface create/destroy hooks. And if we go nuts we could even expand
rendercopy to do some of the format conversions for us on the GPU.

For the time being, I think it's probably better to just check for C8
in the test and skip the cairo stuff entirely. Since this is just for
the bad-format test we don't actually need the fb to have any real
content.

I think it would be cleaner to have some kind of data->expected_error
and then do

if (data->expected_error) {
	igt_assertt(ret, data->expected_error);
	contine;
}

That way it's obvious which subtests expect an error and which don't.

gen >= 10 is a more customary way of writing this. The comment is
redundant.

I wonder where we're resetting data.override_tiling/fmt etc. between
the subtests? Maybe we're not and this whole thing is super buggy if you
do multiple subtests in the same run?
