We unified the Freescale pci/pcie initialization by changing the fsl_pci
to a platform driver. In previous PCI code architecture the initialization
routine is called at board_setup_arch stage. Now the initialization is done
in probe function which is architectural better. Also It's convenient for
adding PM support for PCI controller in later patch.
Now we registered pci controllers as platform devices. So we combine two
initialization code as one platform driver.

The Freescale hypervisor does not allow guests to write to the timebase
registers (virtualizing the timebase register was deemed too complicated),
so don't try to synchronize the timebase registers when we're running
under the hypervisor.
This typically happens when kexec support is enabled.

e500mc cannot doze or nap due to an erratum (as well as having a
different mechanism than previous e500), but it has a "wait" instruction
that is similar to doze.
On 64-bit, due to the soft-irq-disable mechanism, the existing
book3e_idle should be used instead.

Add support for the ePAPR-compliant Freescale hypervisor (aka "Topaz") on
the Freescale P3041DS, P4080DS, and P5020DS reference boards.

Several changes on PCIe support on P3041DS/P4080DS/P5020DS boards:
* Add support for "fsl,qoriq-pcie-v2.2" needed by P3041 & P5020
* Removed support for setting primary_phb_addr as we have no ISA need
* Add PCI controller to of_platform_bus_probe (for EDAC)
* Cleanup building w/SWIOTLB off on P4080DS (not stricly PCIe related)

Add basic support for the P4080 DS reference board. None of the data
path devices (ethernet, crypto, pme) are support at this time.
