mt6577-uart has two clocks. Please fix this.
I would appreciate if you could rebase on the mediatek for-next branch 
(especially for 3/3), which will make it easier for me to take this.

Those two real clocks which UART requires will be updated once the
MT7622 clock driver and the relevant binding header are all ready.
So currently the UART is using dummy clock node instead.

Is it allowed?

O.K. I will rebase on your tree

Yes, no problem with dummy clocks at this point in time, but please 
stick to the binding.
