[PATCH] hw_random: omap3-rom-rng.c: Remove obsoleted functions

[PrasannaKumar Muralidharan]

Remove omap3_rom_rng_data_present method as it was returning 1 always.
Use .read callback instead of .data_read callback. This avoids use of
obsolete callbacks.

This patch is not tested with hardware as I don't have access to it.
