The symbol "GPIO24_SSP1_SFRM" is defined in both mfp-pxa27x.h and
mfp-pxa25x.h. Since the macro is not actually used in the cm-x2xx.c
file, but it includes both headers, a safe workaround should be
to just undefine it from the .c file. This is a bit hacky and
the headers should be fixed to not both define it, but for now
it gets us around an annoying warning.
Without this patch, building cm_x2xx_defconfig results in:
In file included from arch/arm/mach-pxa/include/mach-pxa/pxa27x.h:7:0,
from arch/arm/mach-pxa/cm-x2xx.c:25:
