Subject: [PATCH v2 0/5] Use Device Lifecycle managed functions in TI R5 Remoteproc driver

This series uses various devm_ helpers to simplify device removal path in
ti_k3_r5_remoteproc driver. This is the first series in the TI K3
Remoteproc refactoring as long planned since [0].

Testing Done:
1. Tested boot of R5F remoteprocs in MCU and MAIN voltage domain in both
IPC-Only mode and Kernel remoteproc mode in all Jacinto K3 devices.
2. Tested Lockstep, Split and Single-CPU Mode configuration (wherever
applicable) of R5F remoteprocs in all Jacinto K3 devices.
3. Tested shutdown of R5F remoteprocs from Linux userspace and also by
executing `modprobe -r ti_k3_r5_remoteproc`.
4. Tested that each patch in this series generates no new warnings/errors.

v2: Changelog:
1. Re-ordered patches in the series to use devm functions starting from
the last called function in remove(), to ease review. [Andrew]
2. Fixed a missing return after dev_err_probe() call in [PATCH v2 3/5]
("remoteproc: k3-r5: Use devm_ioremap_wc() helper"). [Andrew]
3. Removed redundant rproc_del() call in [PATCH v2 4/5] ("remoteproc:
k3-r5: Use devm_rproc_add() helper").
