ARM64: dts: meson: reduce odroid-c2 eMMC maximum rate
commitc04ffa71ff
upstream. Different modules maybe installed by the user on the eMMC connector of the odroid-c2. While the red modules are working without an issue, it seems some black modules (apparently Samsung based) are having issue at 200MHz While the tuning algorithm introduced in v4.14 enables high speed modes on every other tested designs, it seems a problem remains for this particular combination of board and eMMC module. Lowering the maximum frequency of the eMMC on this board until we can figure out a better solution. Fixes:d341ca88ee
