ARM: tegra: pull Tegra114 SoC DT from Linux v4.7

The primary benefit of this change is that it adds all missing clocks and
resets properties to peripherals. This will allow peripheral drivers to
migrate to the standard clock and reset APIs in the future.

Main changes:
* Conversion of SPI nodes to standard DMA bindings. U-Boot doesn't use
  DMA so isn't affected.
* Split of EHCI and USB PHY nodes. The EHCI nodes continue to contain all
  information required by U-Boot, so U-Boot is not affected.
* Boards need to define the clk32k_in clock that feeds the Tegra PMC.
* Addition of tegra114-mc.h since tegra114.dtsi now includes it.
* Conversion of many magic numbers to named defines.
* Addition of many nodes not used by U-Boot.
* Node sort order fixes.

Remaining deltas relative to the Linux DT:
* USB node compatible values in U-Boot explicitly list Tegra114 values
  whereas the kernel does not. I'll send a kernel patch to correct this.
