Subject: [PATCH v6 0/2] Extend SSR notifications framework

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
arguments.

Changelog:

v6 -> v5:
- Fix mutec locking and naming convention

v5 -> v4:
- Make qcom_ssr_get_subsys static function
- Fix mutex locking
- Fix function comments

v4 -> v3:
- Fix naming convention 

v3 -> v2:
- Create a global list of per remoteproc notification data structure
- Pass ssr_name and crashed information as part of notification data
- Move notification type enum to qcom_rproc.h from remoteproc.h

v2 -> v1:
- Fix commit text
