Mike Karels ac89220b05 bcm2838_pci.c: Respect DMA limits of controller. 
Fixes for Raspberry Pi 4B PCIe / USB:
- Pass through a DMA tag for the controller.
- In theory the controller can access the lower 3 GB, but testing found
  that unreliable. OpenBSD also restricts DMA to the lowest 960 MiB.
- Rename some constants to be a bit more meaningful.
