Subject: [PATCH] drm: bridge: synopsys/dw-hdmi: Provide default configuration function for HDMI 2.0 PHY

Currently HDMI 2.0 PHYs do not have a default configuration function.

As these PHYs have the same register layout as the 3D PHYs we can
safely use the default configuration function. If, for some reason,
the PHY is custom this change will not make any impact because
in configuration function we prefer the pdata provided configuration
function over the internal one.

This patch is based on today's drm-misc-next branch.
