qcacmn: Process get_cu_for_each_subbw driver command

1. Read the new service capability:
WMI_SERVICE_CCA_BUSY_INFO_FOREACH_20 MHz: Via this host knows
whether FW supports reporting of CCA busy info for each 20 MHz
subband of wideband scan channel or not.

WMI_SERVICE_VDEV_PARAM_CHWIDTH_WITH_NOTIFY_SUPPORT: Via this
host knows whether FW supports VDEV param channel width switch
with OMN/OMI notification or not

2. Register osif callback to send scan done indication to upper
layer

3. Add 2 new scan flags pause_home_channel and
report_cca_busy_for_each_20 MHz
