[PATCH 5/5] remoteproc: ti_k3: Use devm_of_reserved_mem_device_init()

[Mukesh Ojha <mukesh.ojha@oss.qualcomm.com>]

Replace the hand-rolled devm wrapper (k3_mem_release +
devm_add_action_or_reset) with the standard
devm_of_reserved_mem_device_init(), letting the device resource
manager handle cleanup automatically. Remove the now-unused k3_mem_release
exported symbol.
