Update as follows:

Xilinx R5 Device Tree Bindings
- update typos and style
- add compat string for singular r5 core to accomodate
devm_of_platform_populate

Remoteproc Driver:
- remove zynqmp_r5_rproc::dt_node and replace usage with
zynqmp_r5_rproc->dev->of_node throughout file
- emulate TI K3 R5 probe use of devm_of_platform_populate to set devices for
each R5 core's corresponding remoteproc device
- replace zynqmp_r5_rproc var name 'core' to 'z_rproc' throughout file for
consistency
- update indentation
- remove unused var in zynqmp_r5_remoteproc_probe
- update typo in Kconfig
