drm/tegra: sor: Add HDMI support

The SOR1 introduced on Tegra210 supports HDMI 2.0 and DisplayPort. Add HDMI support and name the debugfs node after the type of SOR. The SOR introduced with Tegra124 is known simply as "sor", whereas the additional SOR found on Tegra210 is known as "sor1". Signed-off-by: Thierry Reding <treding@nvidia.com>
