Just like other Exynos5 family SoCs, this one has four UARTs. Configure
clocks for UART3 and enable it.

This patch landed in linux-next[1] and kernelci.org found a boot
regression on the exynos5410-odroidxu[2], where it looks like it's
faulting in clk_prepare().  Bisecting pointed to this patch.  I added
"status = disabled" back into the DTS on top of next-20160601[3] and
verified my odroid-XU to be booting fine again.

Hi,

Thanks for report. Indeed the patch brings up to the light an issue in
serial driver. Fixed here:

I left the commit in my tree as it is correct (strictly speaking).
Sorry for any trouble it makes.

Best regards,
Krzysztof
