SubjectRe: [PATCH] arm64: dts: rockchip: include uhs support for rockpro64

Enabling this UHS support makes 'reboot' hang when booting the RockPro64
from SD card. It would work when booting from eMMC, or with a modified
ATF which does a power cycle on reboot.

But for general use it is not save to enable UHS support, or did I miss
some recent changes?
