[ARM PATCH] 1713/1: pxa2xx_udc (4/5) mach-pxa/lubbock.c updates

Patch from David Brownell

This adds basic lubbock-specific customization for the UDC driver,
and makes it use INIT_MACHINE.

Depends on the INIT_MACHINE patch and the UDC platform_data patches
(#1, #3 in this series).

Be careful of patch conflicts applying to other kernels, mostly due
to different platform devices being listed.
