[ Upstream commit 9d955478a89b4a1ff4e7442216f2822dee8fde73 ]
According to the datasheet the allowed modes for the da9211 regulator are sync and auto mode. This should be changed in the devicetree. This also fix an error message 'BUCKA: invalid regulator-allowed-modes element 0' since value 0 is invalid.
