When the size of dma_addr_t was 32 bits, the compiler warned
about the size of the 32 bit shift being larger than the size
of the data type.

We're giving up all attempts to keep cpu- and device byte ordering separate.
This silences sparse when compiled using

If the command buffer pool is out of space, the code waits until space is
available. However since the condition code tries to allocate a range manager
node while !TASK_RUNNING we get a kernel warning.
Avoid this by pre-allocating the mm node. This will also probably be more
efficient.

Add command buffer support.
Currently we don't implement preemption or fancy error handling.
Tested with a couple of mesa-demos, compiz/unity and viewperf maya-03.
v2:
- Synchronize with pending work at command buffer manager takedown.
- Add an interface to flush the current command buffer for latency-critical
command batches and apply it to framebuffer dirtying.
v3:
- Minor fixes of definitions and typos to address reviews.
- Removed new or moved branch predictor hints.
