remoteproc: tisci: add TI-SCI processor control helper functions Texas Instruments' K3 generation SoCs has specific modules/register spaces used for configuring the various aspects of a remote processor. These include power, reset, boot vector and other configuration features specific to each compute processor present on the SoC. These registers are managed by the System Controller such as DMSC on K3 AM65x SoCs. The Texas Instrument's System Control Interface (TI-SCI) Message Protocol is used to communicate to the System Controller from various compute processors to invoke specific services provided by the firmware running on the System Controller. Add a common processor control interface header file that can be used by multiple remoteproc drivers. The helper functions within this header file abstract the various TI SCI protocol ops for the remoteproc drivers, and allow them to request the System Controller to be able to program and manage various remote processors on the SoC. The common macros required by the R5 remoteproc driver were also added. The remoteproc drivers are expected to manage the life-cycle of their ti_sci_proc_dev local structures.
