rockchip: rk35xx: Remove use of eMMC DDR52 mode
Testing has shown that writing to eMMC using DDR52 mode does not seem to
work on RK356x and RK3588 boards.
A simple test of writing a single block to e.g. sector 0x4000 fails:
# Rescan using DDR52 mode
=> mmc rescan 4
# Write a single block to sector 0x4000 fails with ERROR
=> mmc write 20000000 4000 1
With the MMC_SPEED_MODE_SET Kconfig option enabled.
Fix this by removing the mmc-ddr-1_8v prop from sdhci nodes in affected
board u-boot.dtsi files.
