[PATCH v3 10/11] arm: u8500: Give Golden panel regulators unique names

The Golden device tree gives both fixed panel supplies the same
regulator-name. U-Boot requires regulator names to be unique and aborts
driver-model initialization when binding the second supply.

Add a U-Boot overlay assigning distinct names to the 1.8 V and 3.0 V
supplies. Include the common U8500 overlay since a board-specific
overlay takes precedence over it.
