ARM: kirkwood: disable dcache for Kirkwood boards
Prior to commit 93b283d49f93 ("ARM: CPU: arm926ejs: Consolidate cache routines to common file") the kirkwood boards didn't have and dcache support. The network and usb drivers rely on this. Set CONFIG_SYS_DCACHE_OFF in the Kirkwood specific config.h.
