remoteproc updates for v5.14

This adds support for controlling the PRU and R5F clusters on the TI
AM64x, the remote processor in i.MX7ULP, i.MX8MN/P and i.MX8ULP NXP and
the audio, compute and modem remoteprocs in the Qualcomm SC8180x
platform.

It fixes improper ordering of cdev and device creation of the remoteproc
control interface and it fixes resource leaks in the error handling path
of rproc_add() and the Qualcomm modem and wifi remoteproc drivers.

Lastly it fixes a few build warnings and replace the dummy parameter
passed in the mailbox api of the stm32 driver to something not living on
the stack.
