[igt-dev] [PATCH i-g-t] tests/addfb: Switch to Y tiling for "bo-too-small-due-to-tiling" test

[Dhinakaran Pandiyan]

The test kms_addfb_basic/bo-too-small-due-to-tiling creates an X tiled
buffer that's smaller than what's needed to support rotation.
Correspondingly, the driver assumes all non-linear buffers can support
90/270 rotation and rejects the smaller X tiled buffer. However, only Y/Yf
can support 90/270 rotation, which means the driver should not be
expecting a buffer than what's needed for X tiled buffers. Fix this
negative test case by switching to Y tiling.
