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

This patch fixes them.

Adding ifdefs makes the code bit ugly and is prone to propagate
further. Not sure if DT will help here, but this patch would be
useful for people trying to build for individual boards.
Compile tested for OMAP3EVM.
