Memory returned by dma_alloc_coherent() should already be zeroed
out, so there's no need to do this explicitly.

Replace all of the generic PCI boilerplate with device_pci_driver().

Don't assume a 1:1 virt to phys mapping, but use the real physical
address returned by the dma alloc function.

The set_ethaddr callback should not modify the MAC address passed to it, so
make it const.

Move to the common streaming DMA ops in order to get rid of
the direct usage of the ARM MMU functions for the cache
maintenance.

This better separates the DMA from the MMU functionality.
Also move all drivers that only depends on asm/mmu.h for the alloc
functions over to the common header.

As a lot drivers currently rely on the 1:1 virt->phys mapping on ARM
we define DMA_ADDRESS_BROKEN to mark them. In order to use them on
other architectures with a different mapping they need proper fixing.

Silence warning about cast from volatile to normal pointer,
as this is the intended bhavior here.

The buffer descriptors are allocated from coherent memory, so there
is no cache maintenance needed. Only tell the compiler that the descriptors
can be modified by the hardware.

The processing of the buffer might change some data, which
will eventually trigger a cache writeback later on, corrupting
data written by the network chip. Clean the cache range
to make sure there is no writeback pending.
