rt2x00: Reorganize RT chipset setting for PCI/SOC devices.

Browse source 
Don't set the RT chipset for a device from within the generic PCI/SOC code,
but rather from the individual drivers, so that individual drivers have
more control over what RT chipset is set.
Preparation for chip handling updates for rt2800 devices.
