[PATCH v2 6/8] drm/sun4i: hdmi: Use the common TMDS char rate constant

[Javier Martinez Canillas <javierm@redhat.com>]

Replace the 165000000 magic number with the shared constant defined
in the <linux/hdmi.h> header.

The old comment referenced "HDMI <= 1.2" but 165 MHz is actually
the maximum TMDS character rate defined by the HDMI 1.0 spec.
