qcacld-3.0: Add support for SAE single pmk validity

Browse Source 
Currently when SAE single pmk lifetime expires, the userspace
issues disconnect. To avoid this, on reaching a threshold value
of the total pmk lifetime, the firmware will clear the single
PMK and initiate a roam scan to perform full SAE and derive
new pmk.

Add changes to:
1. Send the remaining single pmk timeout value in seconds to
firmware.
this is calculated as the diffence in pmk timeout configured by
userspace and the time passed after set_pmksa was done (which is
system timestamp between the set_pmksa timestamp and timestamp at
which RSO command is filled).
2. Add internal roam trigger for SPMK timeout trigger.
3. Set the roam score delta value as 0 for SPMK timeout roam
trigger.
