rng: msm: add support for newer Qualcomm hwrandom IPs

On recent Qualcomm SoCs, the hardware random generator
is initialized and handled by the firmware because shared
between different Execution Environments (EE), thus the
initialization step should be skipped.

Also support the newer "TRNG" found on SM8550 and newer
SoCs that has inbuilt NIST SP800 90B compliant entropic source.
