gpu: host1x: Add MIPI pad calibration DT bindings

Introduce device tree bindings for the MIPI pad calibration controller
found on Tegra SoCs. The controller can be used to perform calibration
of pads used for DSI and CSI peripherals.

NVIDIA Tegra MIPI pad calibration controller
Required properties:
- compatible: "nvidia,tegra<chip>-mipi"
- reg: Physical base address and length of the controller's registers.
- clocks: Must contain an entry for each entry in clock-names.
See ../clocks/clock-bindings.txt for details.
- clock-names: Must include the following entries:
- mipi-cal
- #nvidia,mipi-calibrate-cells: Should be 1. The cell is a bitmask of the pads
that need to be calibrated for a given device.
User nodes need to contain an nvidia,mipi-calibrate property that has a
phandle to refer to the calibration controller node and a bitmask of the pads
that need to be calibrated.
