Subject: [PATCH] ath6kl: enable firmware crash dumps on the AR6004

From: Dan Kephart <[email protected]>

The firmware crash dumps on the 6004 are the same as the 6003. Remove the
statement guarding it from dumping on the 6004. Renamed the
REG_DUMP_COUNT_AR6003 to reflect support on both chips.

I have a similar patch already on my queue:

https://patchwork.kernel.org/patch/9262289/

How does this differ from that? Please _always_ add a changelog so that
people know what has changed. Also remember to add "[PATCH v2]" to the
title.

Since ath6kl only supports the 6003 and 6004, this looks fine to me
and works OK on my platforms.
