The SMD channel is not the primary WCNSS channel and must explicitly be
closed as the device is removed, or the channel will already by open on
a subsequent probe call in e.g. the case of reloading the kernel module.
This issue was introduced because I simplified the underlying SMD
implementation while the SMD adaptions of the driver sat on the mailing
list, but missed to update these patches. The patch does however only
apply back to the transition to rpmsg, hence the limited Fixes.

By moving these client drivers to use RPMSG instead of the direct SMD
API we can reuse them ontop of the newly added GLINK wire-protocol
support found in the 820 and 835 Qualcomm platforms.
As the new (RPMSG-based) and old SMD implementations are mutually
exclusive we have to change all client drivers in one commit, to make
sure we have a working system before and after this transition.

As we're running out of hardware capability flags pretty quickly,
convert them to use the regular test_bit() style unsigned long
bitmaps.
This introduces a number of helper functions/macros to set and to
test the bits, along with new debugfs code.
The occurrences of an explicit __clear_bit() are intentional, the
drivers were never supposed to change their supported bits on the
fly. We should investigate changing this to be a per-frame flag.

Currently, wcn36xx only asks for a TX BA session if it has
already established one for RX. Thus, two wcn36xx devices cannot
do a-mpdu between themselves since they both wait for the other
to go first. Fix this by starting a BA session after a few QoS
data frames have been sent to a STA.

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
