ARM: tegra: implement common DMA and resets DT bindings

Browse Source 
This series converts the Tegra DTs and drivers to use the common/
 standard DMA and reset bindings, rather than custom bindings. It also
 adds complete documentation for the Tegra clock bindings without
 actually changing any binding definitions.
 
 This conversion relies on a few sets of patches in branches from outside
 the Tegra tree:
 
 1) A patch to add an DMA channel request API which allows deferred probe
    to be implemented.
 
 2) A patch to implement a common part of the of_xlate function for DMA
    controllers.
 
 3) Some ASoC patches (which in turn rely on (1) above), which support
    deferred probe during DMA channel allocation.
 
 4) The Tegra clock driver changes for 3.14.
 
 Consequently, this branch is based on a merge of all of those external
 branches.
 
 In turn, this branch is or will be pulled into a few places that either
 rely on features introduced here, or would otherwise conflict with the
 patches:
 
 a) Tegra's own for-3.14/powergate and for-4.14/dt branches, to avoid
    conflicts.
 
 b) The DRM tree, which introduces new code that relies on the reset
    controller framework introduced in this branch, and to avoid
    conflicts.

NVIDIA Tegra124 Clock And Reset Controller
This binding uses the common clock binding:
Documentation/devicetree/bindings/clock/clock-bindings.txt
The CAR (Clock And Reset) Controller on Tegra is the HW module responsible
for muxing and gating Tegra's clocks, and setting their rates.
Required properties :
- compatible : Should be "nvidia,tegra124-car"
- reg : Should contain CAR registers location and length
- clocks : Should contain phandle and clock specifiers for two clocks:
the 32 KHz "32k_in", and the board-specific oscillator "osc".
- #clock-cells : Should be 1.

CAR. The assignments may be found in header file
<dt-bindings/clock/tegra124-car.h>.
- #reset-cells : Should be 1.
In clock consumers, this cell represents the bit number in the CAR's
array of CLK_RST_CONTROLLER_RST_DEVICES_* registers.

* The first 192 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB
* registers. These IDs often match those in the CAR's RST_DEVICES registers,
* but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In
* this case, those clocks are assigned IDs above 185 in order to highlight
* this issue. Implementations that interpret these clock IDs as bit values
* within the CLK_OUT_ENB or RST_DEVICES registers should be careful to
* explicitly handle these special cases.
*
* The balance of the clocks controlled by the CAR are assigned IDs of 185 and
