dts: add ESDHC weird voltage bits workaround

From: Roy Zang <[email protected]>

P4080 ESDHC controller does not support 1.8V and 3.0V voltage. but the host controller capabilities register wrongly set the bits. This patch adds the workaround to correct the weird voltage setting bits. Only 3.3V voltage is supported for P4080 ESDHC controller.
