[PATCH 06/12] ARM: omap2: mark unused functions as __maybe_unused

[Arnd Bergmann]

The omap_generic_init() and omap_hwmod_init_postsetup() functions are
used in the initialization for all OMAP2+ SoC types, but in the
extreme case that those are all disabled, we get a warning about
unused code:

arch/arm/mach-omap2/io.c:412:123: error: 'omap_hwmod_init_postsetup' defined but not used [-Werror=unused-function]
arch/arm/mach-omap2/board-generic.c:30:123: error: 'omap_generic_init' defined but not used [-Werror=unused-function]

This annotates both as __maybe_unused to shut up that warning.
