In regulator.yaml exists .*-supply [1] which practically allows every
char sequence before -supply. In the binding microchip,mcp16502.yaml [2]
each node under the regulators includes all the rules/documentation
from regulator.yaml , so I supposed that it is unnecessary to add
in the binding of those new property.

What is your opinion? Let me know any thoughts.
