dt-bindings: reset: hisilicon,hi3660-reset: Drop providers and consumers from example

Binding examples should generally only cover what the binding covers. A
provider binding doesn't need to show consumers and vice-versa. The
hisilicon,hi3660-reset binding example has both, so let's drop them.

This also fixes an undocumented (by schema) compatible warning for
"hisilicon,hi3660-iomcu".
