Some general rt2800 detection improvements. This make SOC a special
interface, and thus simplifying SOC detection a bit, and unifies
rt2800pci and rt2800usb further in detecting with what kind of 
rt2800 device we are dealing with.

Gertjan van Wingerde (3):
  rt2x00: Introduce SoC interface type.
  rt2x00: Reorganize RT chipset setting for PCI/SOC devices.
  rt2x00: rework RT chipset and revision determination for PCI an SOC
    devices.

Introduce the SoC interface type to detect SoC devices, instead of having
them mimic being PCI devices.
This allows for easier detection of SoC devices.

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.

  To: John W. Linville

The recent rt2800 devices are no longer really identified by their PCI
ID's, but rather by the contents of their CSR0 register. Also for the
other chipsets is the contents of this CSR0 register important.
Change the chipset determination logic to be more aligned with the rt2800
model.
Preparation for the support of rt3070 / rt3090 based devices.

this is very ugly, but apparently it is unavoidable to make rt2800lib free from
PCI and USB specific code... :(

I was about to write about a related issue.  My kernel configuration
only enables rt2800pci and rt73 drivers.  lsmod shows that rt2800lib
depends on rt2x00usb:

# lsmod 
Module                  Size  Used by
rt2800pci               9767  0 
rt2800lib              24194  1 rt2800pci
rt2x00usb               9474  1 rt2800lib
rt2x00pci               5993  1 rt2800pci
crc_ccitt               1445  1 rt2800pci
rt2x00lib              27776  4 rt2800pci,rt2800lib,rt2x00usb,rt2x00pci
mac80211              215322  3 rt2x00usb,rt2x00pci,rt2x00lib
cfg80211              144471  2 rt2x00lib,mac80211
eeprom_93cx6            1520  1 rt2800pci

To be clear, the above dependency was not introduced by the patch.  It
would be nice to straighten it eventually.  Maybe the rt2800lib code
should look whether rt2800 (not the generic rt2x00) has USB or PCI
enabled, both for function calls and for includes.

But I'm happy that rt2800pci is working at all!  It was my first chance
to test it.

Actually, this is a temporary situation, and this chunk can be removed again after
patch 3 of the series has been applied.

I'll create a cleanup patch to exactly to that.

With respect to the USB specific code, I have to look at if there is a way to
resolve that, as the USB specific code is only there in 1 place. Maybe a call-back
function to the bus-specific rt2800 drivers could help here.

Tested with rt73usb and rt2800pci.  wpa_supplicant is working fine.  No
new sparse warnings are introduced.
