Drop the redundant fields from drm_connector_hdmi and point its users to hdmi.funcs->vendor and hdmi.funcs->product instead. The connector registration tests used to verify that both names were stored zero-padded and without any trailing NUL, as the SPD InfoFrame requires. That will be covered by dedicated SPD InfoFrame tests, hence drop the KUNIT_EXPECT_MEMEQ() checks on the removed fields.
