Series ARM: dts: imx6ull: Fix dtbs_check warnings | expand

Commit Message

Currently the dtbs_check for imx generates warnings like this:

serial@7000c000: Unevaluated properties are not allowed
('clock-names', 'clocks', 'dma-names', 'dmas' were unexpected)

So add the missing properties to the devicetree binding.
