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.
