When the system controller firmware denies a request, we are informed
of this by the lack of an acknowledge flag in the response. This is
not always an error in cases when we are only testing for permissions.
Do not print error messages in this path. The TI-SCI API caller will
still print the appropriate message if needed.

plat-k3: Initialize Secure Storage with DKEK

K3 HS devices have a randomly generated 256 bit key written into the
efuses in TI Factory. This key is called a Key Encryption Key (KEK) and
is unique to each device.

KEK is fed in hardware into the AES engine inside DMSC/SMS. The efuses
carrying the KEK are marked as read and write protected. As a result,
KEK is only accessible via the AES engine in DMSC/SMS.

System Firmware provides API to obtain a key derived from KEK(DKEK) for
encryption/decryption which is accessible through TI-SCI protocol.

The DKEK will be used in K3 SOCs to initialize HUK for Secure Storage.

Adds TI_SCI_MSG_SA2UL_GET_DKEK in TISCI protocol to extract the DKEK from
K3 SOCs and initialize HUK.

plat-k3: drivers: Add basic support for TI System Control Interface (TI-SCI) protocol

Texas Instruments System Control Interface (TI-SCI) Message Protocol
is used in Texas Instruments System on Chip (SoC) such as those
in keystone family K3 SoC to communicate between various compute
processors with a central system controller entity.

TISCI message protocol provides support for management of various
hardware entities within the SoC. Add support driver to allow
communication with system controller entity within the SoC using the
Secure Proxy.

Introduce the basic registration and query capability for the
driver protocol as part of this change. Subsequent patches add in
functionality specific to the TI-SCI features.

Further information can be found in TI-SCI documentation:
