Current rsnd driver is assuming Audio DMAC / Audio DMAC peri peri

Then, current DMA path searching method is not understandable, and good
enough for this purpose. This patch update DMA path search method, more
simply.

Sound L/R order of SSI is different from Linux sound data order.
So current rsnd driver is using DALIGN (= data align) to exchange data
align on SSIU. OTOH, CMD/SRC/SSIU have DALIGN register. Now inverted
sound volume will be exchanged if user used volume control on DVC.
Because SSIU which exchanges data align is located after DVC.

To be consistent with other kernel interface namings, rename
of_get_named_gen_pool() to of_gen_pool_get().  In the original function
name "_named" suffix references to a device tree property, which contains
a phandle to a device and the corresponding device driver is assumed to
register a gen_pool object.

Due to a weak relation and to avoid any confusion (e.g.  in future
possible scenario if gen_pool objects are named) the suffix is removed.

Fujitsu Lifebook E780 sets the sequence number 0x0f to only only of
the two headphones, thus the driver tries to assign another as the
line-out, and this results in the inconsistent mapping between the
created jack ctl and the actual I/O.  Due to this, PulseAudio doesn't
handle it properly and gets the silent output.

The fix is to ignore the non-HP sequencer checks.

While the commit [d0a601c2: ALSA: jack: Fix the id uniqueness
check] fixes the wrong string check, it leads to a worse result -- the
loop in get_available_index() goes into an endless loop.  The cause is
that snd_ctl_find_id() returns the object assigned to the numid if
it's set.  Thus it points to the previous entry again.

This patch clears the numid field for the next call properly.
