RPI4 is used device-tree that taken from firmware.
mmcnr at 73e00000 is enabled on device-tree, so it's probed on u-boot side.
Because it's for SDIO interface, it doesn't need to probe.
When SDMA is enabled, mmcnr's probe is always failed.

Below log is unnecessary :
  sdhci_setup_cfg: Your controller doesn't support SDMA!!
  mmcnr at 7e30000 - probe failed: -22
