hwrng: omap3-rom - Remove obsoleted functions
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. Signed-off-by: PrasannaKumar Muralidharan <prasannatsmkumar@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
