remoteproc updates for v6.5

The bulk of these patches relates to the moving to a void-returning
 remove callback.
 
 The i.MX HiFi remoteproc driver gets its pm_ops helpers updated to
 resolve build warnings about "defined but not used" variables in certain
 configurations.
 
 The ST STM32 remoteproc driver is extended to allow using a SCMI reset
 controller to hold boot, and has an error message corrected.
 
 The Qualcomm Q6V5 PAS driver gains a missing "static" qualifier on
 adsp_segment_dump().
