Currently the i2400m driver was resetting by just calling
i2400m->bus_reset(). However, this was missing stopping the TX queue
and downing the carrier. This was causing, for the corner case of the
driver reseting a device that refuses to go out of idle mode, that a
few packets would be queued and more than one reset would go through,
making the recovery a wee bit messy.

To avoid introducing the same cleanup in all the bus-specific driver,
introduced a i2400m_reset() function that takes care of house cleaning
and then calling the bus-level reset implementation.

The bulk of the changes in all files are just to rename the call from
i2400m->bus_reset() to i2400m_reset().

The definitions needed for the wimax stack and i2400m driver debug
infrastructure was, by mistake, compiled depending on CONFIG_DEBUG_FS
(by them being placed in the debugfs.c files); thus the build broke in
2.6.29-rc3 when debugging was enabled (CONFIG_WIMAX_DEBUG) and
DEBUG_FS was disabled.

These definitions are always needed if debug is enabled at compile
time (independently of DEBUG_FS being or not enabled), so moving them
to a file that is always compiled fixes the issue.

Expose knobs to control the device (induce reset, power saving,
querying tx or rx stats, internal debug information and debug level
manipulation).
