feat(firme): implement FIRME IDE key management service
Add support for IDE key management service in FIRME.
This implements the FIRME_IDE_KEYSET_PROG, FIRME_IDE_KEYSET_GO,
and FIRME_IDE_KEYSET_STOP ABIs in blocking mode. These ABIs implemented
in EL3 firmware provide a standardized mechanism for managing IDE keys
through the platform IMPDEF key programming interface at a PCIe Root
Port (RP).
