omap: add support for the TRNG Hardware Accelerator
According to TI docs (Processor SDK Linux Getting Started Guide)
the Random Number Generator hardware is found on
OMAP16xx, OMAP2/3/4/5, AM33xx/AM43xx boards. It already
defined in device tree files. Let's enable it.
Some tests:
root@RTS1_OI:~# rngtest -c 1000 </dev/hwrng
rngtest 6.10
