ARM: sa11x0/assabet: ensure CS2 is configured appropriately
commit f3964fe1c9d9a887d65faf594669852e4dec46e0 upstream. The CS2 region contains the Assabet board configuration and status registers, which are 32-bit. Unfortunately, some boot loaders do not configure this region correctly, leaving it setup as a 16-bit region. Fix this.
