The DMA API requires drivers to call the appropriate dma_set_mask()
functions before doing any DMA mapping. Add this required call to
the AMBA PL08x driver.

vert the DMA mask to a PFN using
the device specific dma_to_pfn() macro. This is the reverse of the
pfn_to_dma() macro which is used to get the DMA address for the device.
This gives us a PFN mask, which we can then check against the PFN
limit of the DMA zone.

This driver doesn't need to directly access DMA masks if it uses the
platform_device_register_full() API rather than
platform_device_register_simple() - the former function can initialize
the DMA mask appropriately.

and using the platform_device_register_full()
avoids some of this explicit initialization.
Convert the driver to use platform_device_register_full(), and as it
makes use of coherent DMA, also call dma_set_coherent_mask() to ensure
that the architecture gets to check the mask.

register_platform_device_full() can setup the DMA mask provided the
appropriate member is set in struct platform_device_info. So lets
make that be the case. This avoids a direct reference to the DMA
masks by this driver.

This means we only try and set the coherent DMA mask if we failed to
set a 32-bit DMA mask, and only if both fail do we fail the driver.
Adjust this so that if either setting fails, we fail the driver - and
thereby end up properly setting both the DMA mask and the coherent
DMA mask in the fallbac

sometimes with buggy error handling, and also allows us identify

This started out as a request to look at the DMA mask situation, and how
to solve the issues which we have on ARM - notably how the DMA mask
should be setup.
However, I started off reviewing how the dma_mask and coherent_dma_mask
was being used, and what I found was rather messy, and in some cases
