qcacmn: Enhance the qca_set_band enum value to BITMAP

Also introduce a new attribute QCA_WLAN_VENDOR_ATTR_SETBAND_MASK
to carry this new bitmask enum. This attribute shall consider the
bitmask combinations to define the respective Band combinations
and substitutes QCA_WLAN_VENDOR_ATTR_SETBAND_VALUE.
