Subject: [PATCH] ARM: OMAP: Fix errors and warnings when building for one
 board

When customizing omap2plus_defconfig to build for only
one board (omap3evm), I came across these warnings and
errors (filenames truncated):

arch/arm/mach-omap2/board-generic.c:76:20: warning: 'omap4_init' defined but not used
arch/arm/mach-omap2/built-in.o: In function `omap2420_init_early':

This patch fixes them.
