Let the armv7 bus_dma layer and simplebus(4) implementation deal with
DMA remapping in the same way as arm64. This relies on the dma-ranges
property in the device tree and allows us to get rid of the hack for
the Raspberry Pi in the dwctwo(4) driver.

Note that this does not include the hack in simplebus(4) that we have on
arm64 since firmware that has the dma-ranges is in widespread use now.

The "#address-cells" and "#size-cells" properties define the size
of the memory address and length information. The root node passes
this information down to the children and it can be overwritten by
other nodes inbetween. Pass these properties as part of the fdt
attach args, so that we can grab that information quickly inside
the drivers.

None of the mainbus child devices care about getting a bus_space_tag_t from
its parent, because they know better; so don't bother providing one, which
allows more unused code to go to the Attic.

While there, redo the config machinery for mainbus child devices, to bring
it to our current standards. This also allows them to be disabled in UKC,
should there be a need for this in the future.
