dts: add ESDHC weird voltage bits workaround

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.
