qcacld-3.0: Introduce new ini for dual sta roaming

Browse Source 
Add new ini enable_dual_sta_roam_offload to enable/disable dual
sta romaing feature. Enabling this ini will allow firmware to
roam on both the vdev if firmware supports dual sta roaming and
the hw is dbs capable.

This ini will be checked in the dual sta roaming offload state
machine to enable roaming on both the STA or to fallback to the
current implementation where first connected sta will have rso
enabled.

/**
* send_vdev_set_pcl_cmd_tlv() - Send WMI_VDEV_SET_PCL_CMDID to FW
* @wmi_handle: wmi handle
* @params: Set VDEV PCL params
*
* WMI_VDEV_SET_PCL_CMDID provides the Preferred Channel List (PCL) to WLAN
* firmware. The roaming module is the consumer of this information
* in the WLAN firmware. The channel list will be used when a VDEV needs
* to migrate to a new channel without host driver involvement. An example of
* this behavior is Legacy Fast Roaming (LFR 3.0).
*
* WMI_VDEV_SET_PCL_CMDID will carry only the weight list and not the actual
* channel list. The weights corresponds to the channels sent in
* WMI_SCAN_CHAN_LIST_CMDID. The channels from PCL would be having a higher
* weightage compared to the non PCL channels.
*
* When roaming is enabled on STA 1, PDEV pcl will be sent. When STA2 is
* up, VDEV pcl will be sent on STA 1 after calculating pcl again applying
* the bandmask and VDEV pcl will be sent for STA2. When one of the STA
* is disconnected, PDEV pcl will be sent on the other STA again.
*
* Return: Success if the cmd is sent successfully to the firmware
