Log Message:
Snapshot of work in progress on support for multiple display outputs.
The display configuration comes from the fex script as defined
in http://linux-sunxi.org/Fex_Guide, section disp_init.
There is some code to convert lcd0_para/lcd1_para to properties but
it's not used yet.

At this time only mode 0 (debe0->tcon0->hdmi) works.
debe0->tcon1->hdmi and debe1->tcon0->hdmi both gives a valid HDMI
signal but completely blank screen. AWIN_TCON1_BLUEDATA gives a blue screen
in both cases so tcon1->hdmi works. I suspect that, for some reason
setups other than debe0->tcon0 are not configured properly, and
the tcon is reading all-1 bits instead of the expected debe output.
