[PATCH v4 2/2] drivers: crypto: caam: i.MX8ULP donot have CAAM page0 access

[Pankaj Gupta <pankaj.gupta@nxp.com>]

iMX8ULP have a secure-enclave hardware IP called EdgeLock Enclave(ELE),
that control access to caam controller's register page, i.e., page0.

At all, if the ELE release access to CAAM controller's register page,
it will release to secure-world only.

Clocks are turned on automatically for iMX8ULP. There exists the caam
clock gating bit, but it is not advised to gate the clock at linux, as
optee-os or any other entity might be using it.
