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).

v3:
- update zynqmp_r5 yaml
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

v3:
- add xilinx-related platform mgmt fn's instead of wrapping around
function pointer in xilinx eemi ops struct
v4:
- add default values for enums

zynqmp_r5_remoteproc::zynqmp_r5_probe if the index is valid
- remove uneven dev_dbg/dev_err fn calls
v15:
- change lockstep mode device tree property from acting as
boolean, to instead being used as, if it is present, then r5 is in lockstep
mode. otherwise in split.
- add safeguard for if 2 rpu rem

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).
