Aaro Koskinen 4c374af5fd powerpc/dma-iommu: Fix IOMMU window check 
Checking for device mask to cover the whole IOMMU table is too strict.
IOMMU allocators should handle mask constraint properly for each
allocation.

The patch enables to use old AirPort Extreme cards on PowerMacs with
more than 1GB of memory; without the patch the driver init fails with:

  b43-pci-bridge 0001:01:01.0: Warning: IOMMU window too big for device mask
  b43-pci-bridge 0001:01:01.0: mask: 0x3fffffff, table end: 0x80000000
  b43-phy0 ERROR: The machine/kernel does not support the required 30-bit DMA mask
