[PATCH 0/4] Add smp2p retrigger support

[Chris Lew <quic_clew@quicinc.com>]

The remoteproc framework keeps interrupts disabled until it powers on a
remote proc to prevent spurious interrupts. There is a case where the
remote proc can finish booting before remoteproc enables the interrupt.
If this happens, the remoteproc framework will miss the notification
and eventually timeout waiting for the remoteproc to finish "booting".

Add support into smp2p to retrigger an interrupt if it was missed while
the interrupt was disabled. The interrupt should retrigger once the
interrupt is enabled. This will make the bootup sequence for remoteproc
less racy.
