[PATCH v2 00/12] remoteproc: stm32: Add support for synchronising with M4

This patchset needs to be applied on top of this one [1].

It refactors the STM32 platform code in order to introduce support for
synchronising with the M4 remote processor that would have been started by
the boot loader or another entity.

It carries the same functionatlity as the previeous revision but account
for changes in the remoteproc core to support synchronisation scenarios.
Some RB tags have been removed when the content of the patch has strayed
too far from the original version. See patch 3, 8, 9 and 12 for more
details.

Tested on ST's mp157c board.

Thanks,
Mathieu
