b43: Enforce DMA descriptor memory constraintsmaster-2009-11-18
Enforce all device constraints on the descriptor memory region.
There are several constraints on the descriptor memory, as documented
in the specification. The current code does not enforce them and/or
incorrectly enforces them.
Those constraints are:
- The address limitations on 30/32bit engines, that also apply to
the skbs.
- The 4k alignment requirement on 30/32bit engines.
- The 8k alignment requirement on 64bit engines.
