rt2x00: Fix firmware loading regression on x86_64.
Commit 6175ddf06b6172046a329e3abfd9c901a43efd2e changes the way memcpy_toio() works for x86_64, causing firmware loading to fail for some Ralink WLAN devices with the rt2800pci driver since linux 2.6.34. This causes the log message: "phy0 -> rt2800pci_load_firmware: Error - PBF system register not ready.". Fix this by using __iowrite32_copy instead of memcpy_toio().
