[ARM] 3674/1: ep93xx: add cirrus logic edb9302 support

Browse Source 
Patch from Lennert Buytenhek

This patch adds support for the Cirrus Logic EDB9302, an evaluation
board based on the Cirrus Logic EP9302 SoC, with 32M RAM, one USB host
port, audio in/out, two serial ports and a 10/100 ethernet interface.

George Kashperko submitted the original patch, this patch is a rewrite
using the newer physmap platform driver.
