There is no SoC-external hardware support needed for the hash1, rng1,
crc1 and cryp1 IP blocks to function. Enable them thus unconditionally
instead of replicating their enablement in board device trees.

Hi Ahmad,
These IPs could be enabled in the secure side. To avoid any concurrency
access, I prefer to keep all that crypto IPs status disable.
For examples, RNG can be managed in OP-TEE, so it will remain disable in
Linux.
BR,
Lionel

You could extend that reasoning (OP-TEE might use them) to all peripherals.
As the device tree is supposed to describe the hardware., I'd assume whether
something is enabled in Linux or OP-TEE should be project-specific configuration
(or fixed up by boot firmware).
But I don't feel too strongly about it. Please dismiss and thanks for the clarification.
Cheers,
Ahmad
