Store the queue idx inside structure data_ring
Store the entry idx inside structure data_entry
This saves us a few calls to ARRAY_INDEX() which is now unused.

This adds TX/RX frame dumping capabilities through debugfs.
The intention is that with this approach debugging of rt2x00 is
simplified since _all_ frames going in and out of the device
are send to debugfs as well along with additional information
like the hardware descriptor.

Based on the patch by Mattias Nissler.
Mattias also has some tools that will make the dumped frames
available to wireshark: http://www-user.rhrk.uni-kl.de/~nissler/rt2x00/Signed-off-by: NIvo van Doorn <IvDoorn@gmail.com>

The chipset debugfs entry already indicates it is about the chipset,
it only makes sense to also display the chipset version in there.

DRV_NAME was always set to the KBUILD_MODNAME value,
lets clean everything up by removing DRV_NAME and just
use KBUILD_MODNAME directly.

Loosely based on the patch by Matthijs Kooijman,
this will add the dev_flags entry into debugfs which
will display rt2x00dev->flags.
This will allow easier debugging of flag handling.
