Subject: [PATCH] rt2x00: add support for different chipset interfaces

Enhance rt2x00 infrastructure by adding explicit information
about used chipset interface to struct rt2x00_chip.

The new field will be used by rt2800 drivers for rt2800 library.

Also add commonly used rt2x00_intf_is_pci() and rt2x00_intf_is_usb()
helpers to make code easier to read (noticed by Ivo van Doorn).
