omapdrm: hdmi4: Correct the SoC revision matching

Browse source

commit 23970e150a upstream.

I believe the intention of the commit 2c9fc9bf45
("drm: omapdrm: Move FEAT_HDMI_* features to hdmi4 driver")
was to identify omap4430 ES1.x, omap4430 ES2.x and other OMAP4 revisions,
like omap4460.

By using family=OMAP4 in the match the code will treat omap4460 ES1.x in a
same way as it would treat omap4430 ES1.x

This breaks HDMI audio on OMAP4460 devices (PandaES for example).

Correct the match rule so we are not going to get false positive match.

Fixes: 2c9fc9bf45 ("drm: omapdrm: Move FEAT_HDMI_* features to hdmi4 driver")
