Remove the SoC restriction code from the OMAP RNG driver. The
integration code in arch/arm/*omap* should handle this. The device
shouldn't be created if it doesn't exist on the currently-booted SoC.
This allows us to remove some OMAP-specific cpu_is_omap*() calls from
the driver. Also, if other OMAP chips have RNGs that can be used
by Linux, there will be no need to modify the driver.
