RPI4 is used device-tree that taken from firmware. mmcnr@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@7e30000 - probe failed: -22
