Change the internal API to allow DMA buffers to be pre-allocated by
...
the device driver instead of happening automagically in the HC driver.
This affects both the HC-USBD interface as well as the USBD-device
interface.
This change will allow DMA buffers to be reused e.g. in isochronous
traffic.
Add isochronous support to the UHCI driver (not for OHCI yet).

Add special memory allocation routines that supports allocation
...
DMA-able memory in small chunks (USB uses a lot of 8 byte chunks).
Using the bus_dma functions directly is inefficient.
