video: tegra: dc: Init hdmi's platform data and fb
1. Change hdmi platform data structure's xres and yres values.
These values were made same as LVDS panel (1366x768). LVDS
runs fix display mode,but HDMI can switch to different modes.
The new values (640x480) are corresponding to HDMI's fallback
mode resolution.
2. Map bootloader's framebuffer content to fb1 also, to
initialize fb1's content, and to avoid black & white
strips when hdmi gets enabled but has no content in fb.
It sometimes causes inconsistency on fb_console mapped on HDMI.
