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.

We cannot put the HW RNG to idle using a timer because we cannot disable
clocks from atomic context. Use a delayed work instead.
Fixes a warning with CONFIG_DEBUG_MUTEXES on Nokia N900 during boot.

A platform_driver does not need to set an owner, it will be populated by the
driver core.

This driver provides kernel-side support for the Random Number
Generator hardware found on OMAP34xx processors.
This driver comes from Maemo 2.6.28 kernel and was tested on Nokia RX-51.
It is platform device because it needs board specific function for smc calls.
