rockchip: rk3568-rock-3a: Sync device tree from linux

Running U-Boot from eMMC on a ROCK 3 Model A result in the following:

  U-Boot SPL 2023.04-rc3 (Mar 11 2023 - 17:24:48 +0000)
  Trying to boot from MMC1
  Card did not respond to voltage select! : -110
  spl: mmc init failed with error: -95
  SPL: failed to boot from all boot devices
  ### ERROR ### Please RESET the board ###

The sdhci node is missing in board device tree, sync device tree from
linux v6.3-rc1 to fix booting from eMMC. Also disable sdmmc2 and uart1
nodes related to using a WiFi and BT module in the M2 slot.
