d678a59d2d Revert "Merge patch series "arm: dts: am62-beagleplay: Fix Beagleplay Ethernet""
When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

785cfde5b3 iommu: Add Apple DART driver
The DART is an IOMMU that is used on Apple's M1 SoC.  This driver
configures the DART such that it operates in bypass mode which is
enough to support DMA for the USB3 ports integrated on the SoC.
