arm64: dts: exynos: Correct UART clocks on Exynos7885 



The clocks in the serial UART nodes were swapped by mistake on
Exynos7885. This only worked correctly because of a mistake in the clock
driver which has been fixed. With the fixed clock driver in place, the
baudrate of the UARTs get miscalculated. Fix this by correcting the
clocks in the dtsi.
