Add QCA vendor command support to set band to driver

Add vendor command to pass SET setband command to the driver and read
the updated channel list from driver when this notification succeeds.
This allows the driver to update its internal channel lists based on
setband configuration.

For merge compatibility it has 3 patches:
844dfeb Add QCA vendor command support to set band to driver
6b0ceee Add QCA vendor definitions for multi-port concurrency
d71bdfb Add QCA vendor command for updating gateway parameters
