ath6kl: Collect residue firmware logs

Collect residue firmware logs following firmware assert.
Firmware sends logs to host once the 1500 byte log buffer
has been filled. At time of assert, there could be residue
logs lying in the firmware. This patch pulls those residue
logs. This would give the full picture of the firmware.

ath6kl: add back beginnings of USB support

John Linville had to revert the part of USB support which was already
in ath6kl due to build problems in commit cb00ec382b ("ath6kl: revert
USB support"). Now that I fixed the build problems properly by adding
ath6kl_core.ko kernel module it's possible to add back the
(incomplete) USB support. This patch is a revert of John's patch and
adds back the USB code which as already in ath6kl, only difference
being minor changes in Makefile and adapting usb.c to new core
function names.

Note that USB support in ath6kl is not complete yet. This code only
makes it possible to boot firmware but as HTC layer does not yet
support USB it's not possible to send any WMI commands nor data
packets to the firmware. That will be added soon.

ath6kl: get rid of AR_DBG_LVL_CHECK()

We don't need it as debug calls already have a log level and compiler
should be smart enough to optimise away the code when ath6kl debug code
is not enabled. Also it makes it easier to abstract core code to
ath6kl_core.ko.

In ath6kl_dump_registers() I had to change the debug level from ANY to IRQ
as I removed the AR_DBG_LVL_CHECK() check before calling the function.
