[igt-dev] [PATCH i-g-t v2] tests/kms_cursor_crc: Limit cursor size based on platform capability.

[Karthik B S <karthik.b.s@intel.com>]

Limiting the cursor size of subtests to the maximum size listed as per
the platform capability, so that we can avoid skipping of subtests.

Instead of spliting into subtests based on cursor size,
here spliting of subtests is done based on functionality.
Maximum size of cursor is restricted at run time based
on platform capability.

v2: Keep platform capability fetch inside igt_fixture.
