[igt-dev] [PATCH] tests/kms_addfb_basic: Test addfb2 with DRM_FORMAT_C8 only if supported.

[Mark Yacoub <markyacoub@chromium.org>]

From: Mark Yacoub <markyacoub@google.com>

[Why]
Some devices such as Trogdor do not support DRM_FORMAT_C8 pixel format.
Skip any addfb2 test on such devices that is expected to succeed such as
subtest size-max.

[How]
Only run the check on devices with DRM_FORMAT_C8 support

Tested on Trogdor.
