There is no need to use rng-tools for feeding random data into kernel
entropy pool as hw_random core handles it. Documentation suggested that
rng-tools is required which is incorrect. So remove it.

Hmm, the tool still exists and can still be used to feed /dev/random.
Feeding /dev/random directly from the kernel is just one way of
using hwrng.
So rather than removing it perhaps you can modify it to state that
the kernel can now feed /dev/random as an option.

But it is the default way.

As it is not required I think stating it is going to create confusion.
Users may not know whether rng-tools is optional or necessary for
feeding kernel entropy pool.
