Our new tv mode option allows to specify the TV mode from a property.
However, it can still be useful, for example to avoid any boot time
artifact, to set that property directly from the kernel command line.
Let's add some code to allow it, and some unit tests to exercise that code.

With the introduction of KUnit, IGT is no longer the only option to run
the DRM unit tests, as the tests can be run through kunit-tool or on
real hardware with CONFIG_KUNIT.
Therefore, remove the "igt_" prefix from the tests and replace it with
the "drm_test_" prefix, making the tests' names independent from the tool
used.

Expecting to observe a specific value, when the function responsible for
setting the value has failed will lead to extra noise in test output.
Use assert when the situation calls for it.
Also - very small tidying up around the changed areas (whitespace).
v2: Leave out the locals (drm_connector is huge) (lkp)

Negative tests can be expressed as a single parameterized test case,
which highlights that we're following the same test logic (passing
invalid cmdline and expecting drm_mode_parse_command_line_for_connector
to fail), which improves readability.
v2: s/negative/invalid to be consistent with other testcases in DRM

Considering the current adoption of the KUnit framework, convert the
DRM cmdline parser selftest to the KUnit API.
