qcacmn: Send idle and disconnect roam parameters to firmware

Add support for new wmi command WMI_ROAM_DEAUTH_CONFIG_CMDID to
send disconnect roam trigger parameters and the new wmi command
WMI_ROAM_IDLE_CONFIG_CMDID is used to send the idle roam trigger
parameters.

Update the idle roam and disconnect roam parameters and send them
on the new wmi commands over wmi.

Change-Id: I57acb90266d506d37dcbb58d50ef23fadc439e46
CRs-Fixed: 2431502
