I got some build error like below while executing "make omap2plus_defconfig".

  CC      arch/arm/mach-omap2/board-2430sdp.o
arch/arm/mach-omap2/board-2430sdp.c: In function 'omap_2430sdp_init':
arch/arm/mach-omap2/board-2430sdp.c:247: error: 'GPIOF_OUT_INIT_LOW' undeclared (first use in this function)
arch/arm/mach-omap2/board-2430sdp.c:247: error: (Each undeclared identifier is reported only once
arch/arm/mach-omap2/board-2430sdp.c:247: error: for each function it appears in.)
make[1]: *** [arch/arm/mach-omap2/board-2430sdp.o] Error 1
make: *** [arch/arm/mach-omap2] Error 2

This patch fixes the build error.
