[PATCH] arm64: dts: rockchip: Update eMMC for NanoPi R5 series

Add the 3.3v and 1.8v regulators that are connected to
the eMMC on the R5 series devices, as well as adding the
eMMC data strobe, and enable eMMC HS200 mode as the
Foresee FEMDNN0xxG-A3A55 modules support it.

I had reports from some Fedora users that their eMMC didn't work
on the R5C and this fixes it, the schematic of the eMMC is the
same across all of the R5 series of devices.
