Hello,

The intention of this patchset is to correct the recovery sequence
for Venus v4 (sdm845). Recently has been observed various recovery
failures which leads to unreliable behavior in sys_error handler.
To fix that the sys_error_handler is reworked, proper delays has
been added over pmruntime handling to ensure that the hardware and
encoder/decoder drivers are idle. Also a wrong watchdog code in
threaded irq has been removed. 

regards,
Stan
