The MOXA ART SoC has a DMA controller capable of offloading expensive
memory operations, such as large copies. This patch adds support for
the controller including four channels. Two of these are used to
handle MMC copy on the UC-7112-LX hardware. The remaining two can be
used in a future audio driver or client application.

Without DMA_PRIVATE the driver is not able to allocate more than one channel.
Since it uses dma_get_any_slave_channel that calls private_candidate,
the second allocation fails at
/* some channels are already publicly allocated */
Maybe it should be fixed in the core, but at least this fixes the bug.

i.MX series have inner firmware in its ROM code: when SDMA isn't provided
any firmware from Kernel or rootfs, the default inner ROM firmware will be
activated. However the current driver doesn't assign any script number to
this situation, and those platform running in this case would be broken.

Thus this patch adds a default script number when no external firmware being
loaded so that people would continue to be able to use basic scripts to run
their platform without any firmware.

This reverts commit b1d27c79.

Previously we switched the SSI scriprt to dual-fifo mode to reduce playback
underrun issue, which is only included by SDMA firmware version 2. However,
there are quite a lot people still using version 1 or default firmware in
the ROM code of SoC while these two kinds of firmwares do not support the
dual-fifo script and the audio function on their platform would be broken.

Thus this patch provisionally reverts the dual-fifo script to the original
single fifo script to meet all kinds of users' requirements, including the
version 1/2 or inner ROM firmware.

 7) Several not so common code paths can potentially try to invoke
    packet scheduler actions that might be NULL without checking.  Shore
    things up by either 1) defining a method as mandatory and erroring
    on registration if that method is NULL 2) defininig a method as

Pull regulator fixes from Mark Brown:
 "A small set of driver fixes plus one larger core change which changes
  the way we check to see if we're using DT so that there aren't any
  races between deciding we're using DT and the regulator subsystem
  noticing.

  This makes the new support for substituting a dummy regulator and
  optional regulators work a lot better on DT systems since it ensures
  that we don't trigger probe deferral when we shouldn't which was
  causing bugs in clients"
