The Freescale's Layerscape series processors will use ARM cores.
The LS1's PCIe controllers is the same as T4240's. So it's better
the PCIe controller driver can support PowerPC and ARM
simultaneously. This patch is for this purpose. It derives
the common functions from arch/powerpc/sysdev/fsl_pci.c to
drivers/pci/host/pcie-fsl.c and leaves several platform-dependent
functions which should be implemented in platform files.

Based on upstream master 3.11-rc7
The function has been tested on MPC8315ERDB MPC8572DS P5020DS P3041DS
and T4240QDS boards 

Change log:
v2:
1. Use 'pci' instead of 'pcie' in new file name and file contents. 
2. Use iowrite32be()/iowrite32() instead of out_be32/le32()
3. Fix ppc_md.dma_set_mask setting
4. Synchronizes host->first_busno and pci->first_busno.
5. Fix PCI IO space settings
6. Some small changes according to Scott's comments.

Could you please split this into two patches, where one moves the code,
and the other makes changes to it?
