qcacmn: Add support to get roam scan channel list from fw

Browse Source 
Firmware advertises WMI_SERVICE_ROAM_SCAN_CHANNEL_LIST_TO_HOST_SUPPORT
at the time of initialization, that means host can querry for roam scan
channels list to firmware.

Host driver sends WMI_ROAM_GET_SCAN_CHANNEL_LIST_CMDID to firmware to
querry roam scan channels list and firmware responds with an event
WMI_ROAM_SCAN_CHANNEL_LIST_EVENTID.
