Instead of use special driver for every new panel, we can use the
generic driver and modedb database to specify the timing
information. Now supports 4.3, 5.6 and 7 inch panel.

Hi!
Some time ago there was a discussion about implementing a common
driver for dummy LCDs. I tried the generic-panel and found it can
cover most panels, by adding new entries to modedb.
I've discussed with Thomas and he think this approach might be
cleaner. I'd like to know others opinions.
