b43: fix support for 14e4:4321 PCI dev with BCM4321 chipset
commit 90f91b129810c3f169e443252be30ed7c0130326 upstream. It seems Broadcom released two devices with conflicting device id. There are for sure 14e4:4321 PCI devices with BCM4321 (N-PHY) chipset, they can be found in routers, e.g. Netgear WNR834Bv2. However, according to Broadcom public sources 0x4321 is also used for 5 GHz BCM4306 (G-PHY). It's unsure if they meant PCI device id, or "virtual" id (from SPROM). To distinguish these devices lets check PHY type (G vs. N).
