There is no need to memzero the buffer because dma_alloc_coherent zeros
the memory for us.
This fixes:
BUG: Your driver calls ioremap() on system memory. This leads
<4>to architecturally unpredictable behaviour on ARMv6+, and ioremap()
<4>will fail in the next kernel release. Please fix your driver.

It's not allowed to create an alias of system RAM for DMA. So the memory
used must not be allocated using dma_alloc_coherent but has to be reserved
before using memblock routines.
There is no need to memzero the buffer because dma_alloc_coherent zeros
the memory for us.

To: linux-arm-kernel
... together with the related devices "mx3_camera" and "mx3_sdc_fb".
"mx3_camera" doesn't fit the scheme of the other devices that just are
allocated and registered in a single function because it needs additional
care to get some dmaable memory. So currently imx31_alloc_mx3_camera
duplicates most of imx_add_platform_device_dmamask, but I'm not sure it's
worth to split the latter to be able to reuse more code.
This gets rid of mach-mx3/devices.[ch] and so several files need to be
adapted not to #include devices.h anymore.
