Add support for 'dmesg -c' which clears the dmesg buffer after it has
been printed.  This provides compatibility with other *nix systems
(including Linux).

While here use stdbool booleans for 'all'.

Remove the commented out code I just committed. If we need it, I'll
bring it back uncommented our, or rewrite it.
As requested, move this back to opt-in and list my boards.
Move 'compatible' line out of the common am335x.dtsi and into
the beaglebone-specific .dts file.

Add a new .dts for the BeagleBone Black with more memory,
slightly different pinmux initialization, and with mmchs1
configured (though the latter doesn't quite work yet).
Make the read/write routines default to the newer DS1337 part, but keep
the supported bits board specific.
another minor bugfix in the memory allocator, this time in the free routine.
Fix a VAP BSS node reference in the HT code to actually take a reference
before using said node.

The "blessed" way here is to take a node reference before referencing
anything inside the node, otherwise the node can be freed between
the time the pointer is copied/dereferenced and the time the node contents
are used.

This mirrors fixes that I've done elsewhere in the net80211/driver
stack.

Make sure the holding descriptor and link pointer are both freed during
a non-loss reset.

When the drain functions are called, the holding descriptor and link pointers
are NULLed out.

But when the processq function is called during a non-loss reset, this
doesn't occur.  So the next time a DMA occurs, it's chained to a descriptor
that no longer exists and the hardware gets angry.

Tested:

* AR5416, STA mode; use sysctl dev.ath.X.forcebstuck=1 to force a non-loss
  reset.

TODO:

* Further AR9380 testing just to check that the behaviour for the EDMA
  chips is sane.
