Gcc prints a harmless warning about palmte2_pxa_keys not being used
when the gpio keyboard driver is disabled. The solution is to use
the same #ifdef that is already present in the place where the
symbol is used.
Without this patch, building palmz72_defconfig results in:
/home/arnd/linux-arm/arch/arm/mach-pxa/palmte2.c:128:31: warning:
'palmte2_pxa_keys' defined but not used [-Wunused-variable]
