[ Upstream commit d5712c511cb358ab87f1e884848419ec76a67ab2 ]
WCN3950 is another example of the WCN39xx BT/WiFI family of chips. It requires different firmware files and has different current requirements, so add it as a separate SoC type.
The firmware for these chips has been recently added to the linux-firmware repository and will be a part of the upcoming release: - qca/cmbtfw12.tlv - qca/cmbtfw13.tlv - qca/cmnv12.bin - qca/cmnv13.bin - qca/cmnv13s.bin - qca/cmnv13t.bin
