dt-bindings: mfd: Convert twl-family.txt to json-schema
Convert the TWL[46]030 binding to DT schema format. To do it as a step by
step work, do not include / handle nodes for subdevices yet, just convert
things with minimal corrections. There are already some bindings for its
subdevices in the tree.
