This is a refresh of the patches from an old series [1].
Patch 1 of that series is not required now as [2] serves its purpose.
Patch 2 has been improved and is being posted here.
Patch 3 is unchanged, it has been rebased and posted.

The features being introduced here will be needed by the recently posted PRU
remoteproc driver [3] in addition to the existing Wkup M3 remoteproc driver.
Both of these drivers follow a client-driven boot methodology, with the latter
strictly booted by another driver in kernel. The PRU remoteproc driver will be
supporting both in-kernel clients as well as control from userspace orthogonally.
The logic though is applicable and useful to any remoteproc driver not using
'auto-boot' and using an external driver/application to boot the remoteproc.
