video: tegra: dc: Set default videomode
Set default videomode during the dc probe. This patch enables
HDMI during the probe only and fixes following issues:
1. Until Xinit there was no display on HDMI.
2. Framebuffer console on HDMI needs it to be enabled well before
Xinit.
To avoide un-necessary powering on HDMI,Check HPD and enable HDMI
only if it's present.
