[ARM PATCH] 2371/1: PXA: Add machine support for the Sharp SL-C7xx series of PDAs

Patch from Richard Purdie

Add base machine support for the Sharp SL-C7xx series of PDAs 
(Corgi - SL-C700, Shepherd - SL-C750 and Husky - SL-C760). See 
linux-arm-kernel for a support commitment for this code.

Depends on 2370/1 (SCOOP Driver).
