The rt2800pci driver uses the same [RT]XWI size
for all chipsets, however some chips requires
different values.

The size of the [RT]XWI structures is a constant
value for a given chipset and it does not depend
on the underlying interface. Add a helper function
which returns the correct values for the actual
chipset and use the new helper both in the rt2800usb
and in the rt2800pci drivers. This ensures that both
drivers are using the correct values.

On new 2800 hardware sizes of TXWI & RXIW can be different than TXD
& RXD sizes, so we need to difference between them. Let's define
winfo_size as size of in buffer descriptor (TXWI & RXWI), and desc_size
of as size of additional descriptor - in separate DMA coherent buffer
for PCI hardware (TXD & RXD) and yet another in buffer descriptor for
USB hardware (TXINFO & RXINFO).

Change is rt2x00 wild, but should affect only 2800 driver.

The rt2800pci driver supports the built-in wireless

  make[5]: *** [vmlinux] Error 1

The missing functions are provided by the rt2x00pci
module. This module is only selected by the rt2800pci
driver if PCI support is enabled in the kernel, because
some parts of the rt2x00pci code depends on PCI support.

PCI support is not available on the RT3x5x SoCs because
those have no PCI host controller at all.

Move the non PCI specific code from rt2x00pci into a
separate module. This makes it possible to use that
code even if PCI support is disabled. The affected
functions are used by all of the rt2x00 PCI drivers
so select the new module for those drivers.

rt2800 hardware sometimes reorders tx frames when transmitting to
multiple BA enabled STAs concurrently.

For example a tx queue
	[ STA1 | STA2 | STA1 | STA2 ]
can result in the tx status reports
	[ STA1 | STA1 | STA2 | STA2 ]
when the hw decides to put the frames for STA1 in one AMPDU.

To mitigate this effect associate the currently processed tx status
to the first frame in the tx queue with a matching wcid.

This patch fixes several problems related to incorrect tx status
reporting. Furthermore the tx rate selection is much more stable when
communicating with multiple STAs.
