This set applies on top of [1] and refactors the STM32 platform code in
order to attach to the M4 remote processor when it has been started by the
boot loader.

It carries the same functionatlity as the previeous revision but account
for changes in the remoteproc core to support attaching scenarios.  More
specifically patches 6 to 10 should be given special consideration.

Note that I skipped over v3 and went directly to v4 in order to synchronise
with the remoterproc core patchset[1] that is set at v4.

Tested on ST's mp157c development board.
