drivers: marvell: add support for secure read/write of dfx register-set
Since the dfx register set is going to be marked as secure expose dfx
secure read and write function via SiP services. In introduced misc_dfx
driver some registers are white-listed so non-secure software can still
access them.
This will allow non-secure word drivers access some white-listed
registers related to e.g.: Sample at reset, efuses, SoC type and
revision ID accesses.
