dt-bindings: Updates for v4.15-rc1

This contains the addition of a clock alias which will be used to fix
 the implementation of the SOR1 clock.
 
 Also included are the bindings for the Tegra186 BPMP thermal driver, a
 prerequisite for both the driver and device tree changes.

NVIDIA Tegra186 BPMP thermal sensor
In Tegra186, the BPMP (Boot and Power Management Processor) implements an
interface that is used to read system temperatures, including CPU cluster
and GPU temperatures. This binding describes the thermal sensor that is
exposed by BPMP.
The BPMP thermal node must be located directly inside the main BPMP node. See
../firmware/nvidia,tegra186-bpmp.txt for details of the BPMP binding.
This node represents a thermal sensor. See thermal.txt for details of the
core thermal binding.
Required properties:
- compatible:
Array of strings.
One of:
- "nvidia,tegra186-bpmp-thermal".
- #thermal-sensor-cells: Cell for sensor index.
Single-cell integer.
Must be <1>.
Example:
bpmp {
...
bpmp_thermal: thermal {
compatible = "nvidia,tegra186-bpmp-thermal";
#thermal-sensor-cells = <1>;
};
};
