[PATCH 1/1] dt-bindings: hwmon/regulator: Convert ltc2978.txt to yaml

Convert binding doc ltc2978.txt to yaml format.
Additional change:
- add i2c node.
- basic it is regulator according to example, move it under regulator.

Fix below warning:
arch/arm64/boot/dts/freescale/fsl-lx2160a-clearfog-cx.dtb: /soc/i2c@2000000/i2c-mux@77/i2c@2/regulator@5c:
failed to match any schema with compatible: ['lltc,ltc3882']

-Optional properties:
-- regulators: A node that houses a sub-node for each regulator controlled by
- the device. Each sub-node is identified using the node's name, with valid
- values listed below. The content of each sub-node is defined by the
- standard binding for regulators; see regulator.txt.
-
-Valid names of regulators depend on number of supplies supported per device:
- * ltc2972 vout0 - vout1
- * ltc2974, ltc2975 : vout0 - vout3
- * ltc2977, ltc2979, ltc2980, ltm2987 : vout0 - vout7
- * ltc2978 : vout0 - vout7
- * ltc3880, ltc3882, ltc3884, ltc3886, ltc3887, ltc3889 : vout0 - vout1
- * ltc7880 : vout0 - vout1
- * ltc3883 : vout0
- * ltm4664 : vout0 - vout1
- * ltm4675, ltm4676, ltm4677, ltm4678 : vout0 - vout1
