ASoC: Tegra+WM8903 machine: Add device tree binding

This driver is parameterized in two ways:

a) Platform data, which supplies the set of GPIOs used by the driver.
   These GPIOs can now be parsed out of device tree.

b) Machine-specific DAPM route arrays embedded into the ASoC machine
   driver itself. Historically, the driver picks the appropriate array
   to use using machine_is_*(). The driver now requires this array to
   be parsed from device tree when instantiated through device tree,
   using the core ASoC support for this parsing.

Based on work by John Bonesio, but significantly reworked since then.

ASoC: Refactor some conditions and loop in soc_bind_dai_link()

Transform some loops from:

for_each(x) {
    if (f(x)) {
        work_on(x);
    }
}

to new structure:

for_each(x) {
    if (!f(x))
        continue;

    work_on(x);
}

This will allow future modification of f(x) with less impact to the code.

ASoC: Tegra: Move DAS configuration into DAS driver

Move DAS routing setup into the DAS driver itself. This removes the need
to duplicate this in each machine driver, of which we'll soon have three.

An added advantage is that the machine drivers no longer call the Tegra20-
specific DAS functions by name, so the machine driver no longer needs to
be split up into Tegra20 and Tegra30 versions.

If individual machine drivers need a different routing setup to this
default, they can still call the DAS functions to set that up.

Long-term, DAS will be a codec driver, and user-space will be able to
control its routing, possibly within constraints that the machine driver
sets up. Configuring the DAS routing from the DAS driver is a very slight
move in that direction.

ASoC: Take a pm_runtime reference on DAPM devices that are enabled

As for PCMs take a runtime power management reference to devices that are
in a non-off bias, avoiding the need to do this in individual drivers.

ASoC: Hold runtime PM references to components of active DAIs

Every device that implements runtime power management for DAIs is doing
it in pretty much the same way: in the startup callback they take a
runtime PM reference and then in the shutdown callback they release that
reference, keeping the device active while the DAI is active. Given the
frequency with which this is done and the obviousness of the need to keep
the device active in this period factor the code out into the core, taking
references on the device for each CPU DAI, CODEC DAI and DMA device in the
core.

As runtime PM is reference counted this shouldn't interfere with any
other reference holding by the drivers, and since (in common with the
existing implementations) we don't check for errors on enabling it
shouldn't matter if the device actually has runtime PM enabled or not.
