PM / OPP: Introduce ti-opp-supply driver

Hi,
This is v2 of the series to introduce the ti-opp-supply driver which makes use of the OPP core to enable multiple regulator DVFS and AVS Class0 for TI DRA7 and AM57 platforms. Version 1 of this series can be found here [1].

Very few changes since v1, just added Viresh's acks to patches 1 and 2 and added SPDX license to the ti-opp-supply driver in patch 4.

Pushed updated branch here just in case [2].

Regards,
Dave
