[PATCH 3/8] drm/bridge: dw-hdmi-qp: Use the common TMDS char rate constant

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

Replace the driver local HDMI14_MAX_TMDSCLK define with the shared
constant defined in the <drm/display/drm_hdmi_helper.h> header.

The local define incorrectly referenced HDMI 1.4, but the 340 MHz
maximum TMDS character rate was actually introduced in HDMI 1.3.
