qcacmn: Provide WMI support for AP channel switching enhancements

Provide WMI support for AP channel switching enhancements.

As part of FR50393, AP is provided with the ability to notify
capable connected peers to follow it to the new channel bandwidth.

This change provides WMI support for sending required parameters to
the firmware to update the peer list internally with the MAC address
of the capable peer along with it's new channel width.
