arm64: dts: rockchip: remove num-slots property from rk3328-nanopi-r2s-plus

num-slots was not part of the dw-mmc binding and the last slipage of
one of them seeping in from the vendor kernel was removed way back in
2017. Somehow the nanopi-r2s-plus managed to smuggle another on in the
kernel, so remove that as well.
