Most Qualcomm platforms contain a pseudo random number generator
hardware block. Enable the driver for this block.

This enabled and loads the driver, but doesn't enable the usage.

We also need CONFIG_CRYPTO_RNG2 but that gets selected so that part is
fine. For userspace we need CONFIG_CRYPTO_USER_API_RNG to be added so
that kernel exports interface to users. So can you add that as well.

Thanks
