rockchip: rk3588-rock-5b: Fix sdmmc boot

Running U-Boot from a SD-card on ROCK 5 Model B fails to load atf using
DMA and prints debug_uart messages.

  <debug_uart>

  <debug_uart>

  U-Boot SPL 2023.04-rc3 (Mar 12 2023 - 00:30:16 +0000)
  Trying to boot from MMC1
  ## Checking hash(es) for config config-1 ... OK
  ## Checking hash(es) for Image atf-1 ... sha256 error!
  Bad hash value for 'hash' hash node in 'atf-1' image node
  mmc_load_image_raw_sector: mmc block read error
  SPL: failed to boot from all boot devices
  ### ERROR ### Please RESET the board ###

Use fifo-mode to disable DMA in SPL, add same-as-spl to boot-order and
remove DEBUG_UART_ANNOUNCE option to fix this.
