Subject: [PATCH] omap2: mark omap_init_rng as __init

I found this section mismatch when building with an older
compiler release:

WARNING: vmlinux.o(.text+0x3051c): Section mismatch in reference from the function omap_init_rng() to the function .init.text:omap_device_build()

Obviously this one function should be __init as well. Normally
we don't get a warning as the function gets inlined into its
caller.
