firmware: xilinx: Add ZynqMP firmware ioctl enums for RPU
configuration.
firmware: xilinx: Add shutdown/wakeup APIs
firmware: xilinx: Add RPU
Add shutdown/wakeup a resource eemi operations to shutdown
or bringup a resource.
Note alignment of args matches convention of other fn's in this file.
The reason being that the long fn name results in aligned args that
otherwise go over 80 chars so shift right to avoid this

of string name
- print device tree nodes with %pOF instead of %s with node name field
- update tcm release to unmap VA
- handle r5-1 use case
- device tree binding r5 node to have link to TCMs via meta-memory-regions
property
- fix device tree binding so no warnings from 'make dt_binding_check'
, memory access
and R5 lifecycle management. The interface to this manager is done in this
driver via zynqmp_pm_* function calls.

v3:
- update zynqmp_r5 yaml
This patch adds APIs to access to configure RPU and its
processor-specific memory.
That is query the run-time mode of RPU as either split or lockstep as well
as API to set this mode. In addition add APIs to access configuration of
the RPUs' tightly coupled memory (TCM).
