Currently, the delayed IRQ handling for PCM streams is managed in a
single work embedded in hda_intel, but this is basically a per-stream
thing. Due to the single work, we can't cancel the work properly at
closing each stream, for example.
For making the IRQ pending work to be stream-based, this patch changes
the following:
- An extended version of azx_dev (i.e. the hd-audio stream object) is
defined for snd-hda-intel
- The irq_pending flag and irq_pending_work are moved to
hda_intel_stream, so that they can be hda-intel stream specific
- The stream creation and assignment are refactored so that
snd-hda-intel can handle individually;
the snd-hda-intel specific workaround for stream tags is also moved
to snd-hda-intel itself instead of the common code
- The irq pending work is canceled properly at free / shutdown
While we're at it, changed the bit field flag to bool, as the bit
field doesn't help much in our case.

Now HD-audio controller drivers are moved into sound/hda/controllers
directory as a part of HD-audio code reorganization. Most of drivers
are independent from PCI bus, hence it makes more sense to put under
sound/hda.
The hda_ prefix is dropped from most of files at moving, as it's
more or less superfluous.
