Enable LLCC/DDR/DDR_QOS dvfs through the Qualcomm's SCMI vendor protocol.

Signed-off-by: Sibi Sankar <quic_sibis@quicinc.com>

V1:
* Use alternate bindings. [Dmitry/Konrad]
* Cleanups/Fixes suggested for the client driver. [Dmitry/Konrad/Cristian]
* Use opp-tables instead of memfreq-tbl. [Dmitry/Konrad]
* Add support for DDR_QOS mem_type.
