[igt-dev] [PATCH i-g-t v4 2/3] tests/kms_psr2_su: add biplanar selective update tests

[Jouni Högander]

Add biplanar formats (NV12, p010) into selective update test.

v2: Add back skipping of frontbuffer rendering tests
v3: Use hyphen instead of underscore in testnames
v4: Split offset change to own patch
