On non-OMAP2 and non-OMAP3 kernel configs, turn omap2_sdrc_init() into
a no-op.  Otherwise, compilation breaks on an OMAP4-only config with
the current omap-for-linus branch:

arch/arm/mach-omap2/built-in.o: In function `omap2_init_common_devices':
../mach-omap2/io.c:421: undefined reference to `omap2_sdrc_init'

Thanks to Sergei Shtylyov <sshtylyov@mvista.com> for suggesting the use
of a empty static inline function rather than a macro.
