qcacld-3.0: Enable the Partial scan for roam triggers

Browse Source 
Currently the roam scan scheme for each trigger is hardcoded to
either full scan or partial scan followed by full scan. Based on
the new requirement for home scenario,the user space configures
roam scan scheme for various triggers. Add support to send scan
scheme type for indvidual roam triggers enabled from userspace.
The default value of roam scan scheme can be modifed for
below roam triggers:
WMI_ROAM_TRIGGER_REASON_PER,WMI_ROAM_TRIGGER_REASON_BMISS,
WMI_ROAM_TRIGGER_REASON_LOW_RSSI,WMI_ROAM_TRIGGER_REASON_BSS_LOAD,
WMI_ROAM_TRIGGER_REASON_BTM
