qcacmn: Extend qdf_trigger_self_recovery to include psoc granularity

Browse Source 
To undergo self recovery, the driver uses qdf_trigger_self_recovery to
initiate the sequence. Currently, this framework is valid for only a
single psoc driver.

Extend this framework to include support for multiple psoc driver by
providing the psoc on which the recovery has to be undertaken.
