PCI devices on Keystone doesn't have correct dma_pfn_offset set. This

add capability to set the dma configuration such as dma-mask,
dma_pfn_offset,
and dma ops etc using the information from DT. The prior RFCs and
discussions
are available at [1] and [2] below.

Change history:
v3 - addressed comments to re-use of_dma_configure() for PCI
- To help re-use, change of_iommu_configure() function argument
- Move of_dma_configure to of/device.c
- Limit the of_iommu_configure to non pci devices
v2 - update size to coherent_dma_mask + 1 if dma-range info is
missing
- also check the np for null.
v1 - updates based on the comments against initial RFC.
- Added a helper function to get the OF node of the parent
- Added an API in of_pci.c to update DMA configuration of the
pci
device.

Bjorn,
Could you review this series from the PCI subsystem point of view?
Will do, it's in my patchwork queue. I'm just returning after a
couple weeks of vacation, during which I moved across the country, so
it will take me a bit to catch up.
Bjorn
Bjorn,
Thanks and Happy New year!
