Add support for the secondary channel offset IE in channel
switch announcements. This is necessary for proper handling
of CSA on HT access points.
For this to work it is also necessary to convert everything
here to use chandef structs instead of just channels. The
driver updates aren't really correct though. In particular,
the TI wl18xx driver update can't possibly be right since
it just ignores the new channel width for lack of firmware
API.

Pretty much everywhere that uses a trace definition
header that's not in include/trace/events/ uses the
make system for the include path rather than putting
it into the sources, so do that in ath5k as well.
This came up during backporting work (where this is
required), but since all other drivers do it this
way upstream it seemed applicable.

If AR_CRCErr, AR_PHYErr, AR_DecryptCRCErr or AR_MichaelErr is indicated
in the rx status word, but AR_RxFrameOK is also set, the descriptor
contents are typically invalid. This can show up as a warning about
invalid MCS rates in a frame. Even with those checks in place, a
descriptor with invalid MCS rates can still sometimes make it through to
the driver (mostly on older hardware like AR91xx).
Detect such errors in the last descriptor of a frame and discard the
whole frame if present.

As the comment in ath_get_next_rx_buf indicates, if a descriptor with
the done bit set follows one with the done bit cleared, both descriptors
should be discarded, however the driver is not doing that yet.
To fix this, use the rs->rs_more flag as an indicator that the following
frame should be discarded. This also helps with the split buffer case:
if the first part of the frame is discarded, the following parts need to
be discarded as well, since they contain no valid header or usable data.

The functions in the rt2x00mmio module has been
moved from the rt2x00pci module. Each function
uses the rt2x00pci prefix which is a bit confusing.
Use the r2x000mmio prefix for each function to make
it consistent with the module name.
The renamed functions are used by several modules,
and updating the names in all of them would result
in a big patch. In order to keep the patch simple,
add compatibility defines for the old function
names. This allows to update the names in each
module separately. After each module is updated,
the defines can be removed.
