Use KUNIT_EXPECT_MEMEQ to compare memory blocks in replacement of the
KUNIT_EXPECT_EQ macro. Therefor, the statement
KUNIT_EXPECT_EQ(test, memcmp(foo, bar, size), 0);
is replaced by:
KUNIT_EXPECT_MEMEQ(test, foo, bar, size);

The test was constructed as a single function (test case) which checks
multiple conditions, calling the function that is tested multiple times
with different arguments.
This usually means that it can be easily converted into multiple test
cases.
Split igt_check_plane_state into two parameterized test cases,
drm_check_plane_state and drm_check_invalid_plane_state.

The xrgb2101010 format conversion test (unlike for other formats) does
an endianness conversion on the results. However, it always converts
TEST_BUF_SIZE 32-bit integers, which results in reading from (and
writing to) more memory than in present in the result buffer. Instead,
use the buffer size, divided by sizeof(u32).
The issue could be reproduced with KASAN:
./tools/testing/kunit/kunit.py run --kunitconfig drivers/gpu/drm/tests \
--kconfig_add CONFIG_KASAN=y --kconfig_add CONFIG_KASAN_VMALLOC=y \
--kconfig_add CONFIG_KASAN_KUNIT_TEST=y \

The drm_test_dp_mst_sideband_msg_req_decode repeats the same test
structure with different parameters. This could be better represented
by parameterized tests, provided by KUnit.
In addition to the parameterization of the tests, the test case for the
client ID was changed: instead of using get_random_bytes to generate
the client ID, the client ID is now hardcoded in the test case. This
doesn't affect the assertively of the tests, as this test case only compare
the data going in with the data going out and it doesn't transform the data
itself in any way.
So, convert drm_test_dp_mst_sideband_msg_req_decode into parameterized
tests and make the tests' allocations and prints completely managed by KUnit.

The prandom_u32() function has been a deprecated inline wrapper around
get_random_u32() for several releases now, and compiles down to the
exact same code. Replace the deprecated wrapper with a direct call to
the real function. The same also applies to get_random_int(), which is
just a wrapper around get_random_u32(). This was done as a basic find
and replace.

While we have multiple test cases, most of them check multiple
conditions, calling the function that is tested multiple times with
different arguments (with comments that indicate test case boundary).
This usually means that it can be easily converted into multiple test
cases.

and convert all users. Although these are single-plane color formats,
the new interface supports multi-plane formats for consistency with
drm_fb_blit().

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.

Test the conversion from XRGB8888 to RGB332.
What is tested?
- Different values for the X in XRGB8888 to make sure it is ignored
- Different clip values: Single pixel and full and partial buffer
- Well known colors: White, black, red, green, blue, magenta, yellow
and cyan
- Other colors: Randomly picked
- Destination pitch
How to run the tests?
