[ Upstream commit 94ea124aeefe1ef271263f176634034e22c49311 ]
The first SDHC can do DMA like most other peripherals, add the missing iommus entry which is required to set this up.
This may have been working on Linux before since the bootloader configures it and it may not be full torn down. But other software like U-Boot needs this to initialize the eMMC properly.
