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.

Move uart2 bootph-pre-ram and clock-frequency props from board to SoC
u-boot.dtsi. Regular board device tree already enables the uart2 node,
so status prop is dropped from u-boot.dtsi file.
Also remove unnecessary stdout-path = &uart2, regular board device tree
already provide a stdout-path = "serial2:" value.
