[PATCH] imx21ads : avoid overlapping static i/o mappings

The static I/O mappings for the cs89x0 ethernet controller and the
secondary AHB port 1 (SAHB1) overlapped, causing a kernel crash
at startup. This is fixed by mapping the cs89x0 to 0xf6000000 (which
is free to use according to arch/arm/plat-mxc/include/mach/hardware.h).
