dt-bindings: clock: Convert i.MX7D clock to json-schema

* Clock bindings for Freescale i.MX7 Dual

Required properties:

- compatible: Should be "fsl,imx7d-ccm"

- reg: Address and length of the register set

- #clock-cells: Should be <1>

- clocks: list of clock specifiers, must contain an entry for each required

  entry in clock-names

- clock-names: should include entries "ckil", "osc"

The clock consumer should specify the desired clock by having the clock

ID in its "clocks" phandle cell.  See include/dt-bindings/clock/imx7d-clock.h

for the full list of i.MX7 Dual clock IDs.
