subsystem_restart: Always performs soft resets when subsystems crash

Browse Source 
* OEM is using a dirty list and userspace nodes to override restart_level
for some subsystems. Why not just ignore all RESET_SOC and use a soft reset
instead? Nobody wanna to see their device goes randomly reboot sometimes.

* Note that commit 0e27242 is also needed to fix broken irq free when soft
reset the modem.
