net: mvneta: clean txdesc before usage ...

This fixes tx error detection which triggered way too often because the
hardware doesn't seem to clear the error bits on success

net: mvneta: Fix transmit errors due to dirty txdesc ...

Marvell Neta's transmit descriptor (txdesc) is allocated by dma_alloc_coherent()
but not zeroed before calling mvneta_send the first time. This can cause spurious
transmit errors due to improperly set bits in txdesc's cmd_sts field.

Fix initial transmit errors by always writing whole cmd_sts field instead of ORing
the bits.

ARM: move DMA alloc functions to dma.h ...

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.

ARM: change dma_alloc/free_coherent to match other architectures ...

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.
