[ARM] 3671/1: ep93xx: add cirrus logic edb9315 support

Patch from Lennert Buytenhek

This patch adds support for the Cirrus Logic EDB9315, an evaluation
board based on the Cirrus Logic EP9315 SoC, with 64M RAM, two USB host
ports, audio in/out, three serial ports, 10/100 ethernet, and IDE, VGA,
and LCD interfaces.
