The function ttm_bo_put releases a reference to a TTM buffer object. The
function's name is more aligned to the Linux kernel convention of naming
ref-counting function _get and _put.
A call to ttm_bo_unref takes the address of the TTM BO object's pointer and
clears the pointer's value to NULL. This is not necessary in most cases and
sometimes even worked around by the calling code. A call to ttm_bo_put only
releases the reference without clearing the pointer.

This is the most significant part in the patch series.
The bcm2835-audio driver used to queue the commands to vc04 core via
workqueue, but basically the whole accesses to vc04 core are done in
the sleepable context, including the callback calls. In such a case,
rewriting the code using non-atomic PCM ops will simplify the logic a
lot.
This patch does it: all workqueue are gone and each former-work
implementation is now directly called from PCM ops like trigger and
write transfer.
Along with it, the DMA position updater, bcm2835_playback_fifo(), was
also rewritten to use a simpler logic. Now it handles the XRUN and
draining properly by calling snd_pcm_stop() conditionally.
The current position is kept in atomic_t value so that it can be read
concurrently from the pointer callback.
Also, the bcm2835_audio_instance object is allocated at the beginning
of bcm2835_audio_open(). This makes the resource management clearer.
