Subject: [PATCH] regulator: hi655x: Add DT bindings so module autoloads

The hi655x driver is required for mmc/sd functionality on the
96boards hikey, and likely other platforms. When built as
a standalone module it doesn't get automatically loaded because
it is missing the module probe hooks.

Adding that boilerplate so it gets demand loaded.
