Merge branch '2023-10-13-firmware-scmi-updates'

- Fix a memset call in the optee_agent code.

Then to quote the author for the rest of the changes:
This patch series allows users to access SCMI base protocol provided by
SCMI server (platform). See SCMI specification document v3.2 beta[1]
for more details about SCMI base protocol.

What is currently not implemented is
- SCMI_BASE_NOTIFY_ERRORS command and notification callback mechanism

This feature won't be very useful in the current U-Boot environment.
