mci: core: Check return value of dev_add_param_bool ...

Commit 03b59bd changed the
return values of dev_add_param_* to ERR_PTR(-ENOSYS) and broke a few boards.
We have now to care about the return value of dev_add_param_bool() in
mci_register().

Also set the ret variable when dev_add_param_bool() fails.

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

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.
