qcacmn: Add new ini to set min delay btw scan and reason bit-mask

Add ini "min_delay_btw_scans" to set minimum duration allowed between
two consecutive roam scans. Fw should not allow roam scan if duration
between two consecutive roam scan is less than min_delay_btw_scan.

Add ini "roam_trigger_reason_bitmask" to set default value of
bit-mask containing roam_trigger_reasons for which
min_delay_btw_scans constraints should be apply.

Pass value of min_delay_btw_scans and roam_trigger_reason_bitmask
to fw.
