This set of patches gives kernel client drivers the ability to register
for a particular remoteproc's SSR notifications. Also the notifications
are extended to before/after-powerup/shutdown stages.
It also fixes the bug where clients need to register for notifications
again if the platform driver is removed. This is done by creating a
global list of per-remoteproc notification info data structures which
remain static. An API is exported to register for a remoteproc's SSR
notifications and uses remoteproc's ssr_name and notifier block as
