Merge branch 'rproc-linux-5.4.y' of git://git.ti.com/rpmsg/remoteproc into rpmsg-ti-linux-5.4.y

Pull in the updated remoteproc feature branch that brings in a number
of improvements/cleanups to the PRUSS platform drivers. These include:
 - Extend the support for IEP clock muxes to all SoCs (only K3 SoCs
   supported previously).
 - Add YAML bindings for IEP sub-module and corresponding dts nodes
   on all SoCs.
 - Add three new YAML bindings 'ti,pruss-intc.yaml', 'ti,pru-rproc.yaml'
   and 'ti,pru-consumer.yaml' for PRUSS INTC, PRU remoteproc and PRU
   consumers respectively. The corresponding text bindings are dropped.
 - Drop the added pruss_intc_trigger() API, and convert the PRU
   remoteproc driver to direct use an equivalent IRQ subsystem API.

The IEP changes would also require corresponding adjustments to the PRU
Ethernet drivers (out of scope on this tree, changes handled through
the connectivity domain tree).
