crypto: caam - Remove crypto_rng interface

Since the crypto_rng interface for hardware PRNGs is unused and is
redundant with hwrng and the actual Linux RNG, it's being phased out.
Most drivers for it were already removed.  Go ahead and remove the CAAM
support which is one of the only remaining ones.

Note that the CAAM support for hwrng remains in place.  That is the
interface that actually matters.

Note that this code also had several issues, including dlen > 65535
causing corruption of the CAAM descriptor.
