[PATCH] arm64: dts: mt8173-elm: fix supported values for regulator-allowed-modes of da9211

[Dafna Hirschfeld]

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.
