Lucas Stach 4ab6b15a00 dma-direct: don't truncate dma_required_mask to bus addressing capabilities ...

[ Upstream commit d8ad55538a ]

The dma required_mask needs to reflect the actual addressing capabilities
needed to handle the whole system RAM. When truncated down to the bus
addressing capabilities dma_addressing_limited() will incorrectly signal
no limitations for devices which are restricted by the bus_dma_mask.

Fixes: b4ebe60632 (dma-direct: implement complete bus_dma_mask handling)
