[PATCH] rockchip: rk3328: fix booting error for nanopi-r2s

[jason416]

devices can not boot properly during SPL stage by
using microSD card which model is SDSQUNC-032G-ZN6MA.

U-Boot SPL 2021.04 (Jul 02 2021 - 19:50:12 +0000)
Trying to boot from MMC1
mmc_load_image_raw_sector: mmc block read error
SPL: failed to boot from all boot devices

change dts and config to support booting from ultra
high speed microSD card on nanopi-r2s.
