core: console: Allow setting logging verbosity during runtime

The default console can be disabled at runtime for power management. Any
prints after boot from OP-TEE could cause a bus data abort if the UART has
been disabled. Add an option to change the log level after boot has
completed which can be used to disable the console log.

plat-k3: drivers: Add TRNG driver support in AM62L

AM62L contains the EIP76D TRNG IP which was also present in the previous
K3 devices inside the SA2UL accelerator, so the same driver is being
re-used here. But the AM62L does not have SA2UL. The SoC specific
configurations are being set here for AM62L for enabling TRNG.

Refactor the SA2UL and RNG driver to make EIP76D TRNG driver independent
of SA2UL.

Disable TI SCI, secure boot info and HW unique ID support for now, they
will be incrementally at later point in time as the underlying
communication layer is different than AM62x.
