From: Paul Boddie <paul@boddie.org.uk>

Add support for the LCD controller present on JZ4780 SoCs.
This SoC uses 8-byte descriptors which extend the current
4-byte descriptors used for other Ingenic SoCs.

Tested on MIPS Creator CI20 board.

I think this is wrong :)

Oops, that is a side-effect of my patch series editing tool.
It sometimes reverts changes of a previous commit if both
affect the same file. Sorry for that and I should fix it...

I'll send v8.
