Subject: [PATCH 4/9] drm/vc4: hdmi: Rename full range helper

From: Dave Stevenson <dave.stevenson@...pberrypi.com>

The VC4 HDMI driver has a helper function to figure out whether full
range or limited range RGB is being used called
vc4_hdmi_is_full_range_rgb().

We'll need it to support other colorspaces, so let's rename it to
vc4_hdmi_is_full_range().
