drm/tests: Split up test cases in igt_check_drm_format_min_pitch
The igt_check_drm_format_min_pitch() function had a lot of
KUNIT_EXPECT_* calls, all of which ended up allocating and initializing
various test assertion structures on the stack.
This behavior was producing -Wframe-larger-than warnings on PowerPC, i386,
and MIPS architectures, such as:
drivers/gpu/drm/tests/drm_format_test.c: In function 'igt_check_drm_format_min_pitch':
drivers/gpu/drm/tests/drm_format_test.c:271:1: error: the frame size of
3712 bytes is larger than 2048 bytes
So, the igt_check_drm_format_min_pitch() test case was split into three
smaller functions: one testing single plane formats, one testing
multi-planar formats, and the other testing tiled formats.
Fixes: 0421bb0baa84 ("drm: selftest: convert drm_format selftest to KUnit")
