Subject: [PATCH 1/2] auxdisplay: move the ARM LCD driver into auxdisplay

This driver most definately belongs in this subsystem. It is a
simple hardware block wrapping the Hitachi HD44780 LCD into
a system peripheral, and if there is ever going to be shared
code amongst LCD drivers, it will happen in this subsystem,
so move it.

Miguel: if you ACK this I guess I can get it merged through the
ARM SoC tree.
Arnd: another misc exodus I'm trying to engineer.
