The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and
can be confusing when reading the code.
Rename PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY to clarify its used
for system memory mapping purposes.

Add fsl_pci_config_unlock() function to enable a
PCI/PCIe interface configured in agent/endpoint mode to
respond to inbound PCI configuration cycles.

fsl_pci_init.c: In function 'fsl_pci_setup_inbound_windows':
fsl_pci_init.c:122: warning: comparison is always true due to limited range of data type
The check only makes sense if we are CONFIG_PHYS_64BIT

The current code will cause the creation of a 4GB window
starting at 0 if we have more than 4GB of RAM installed,
which overlaps with PCI_MEM space and causes pci_bus_to_phys()
to return erroneous information. Limit the size to 4GB - 1;
which causes the code to create one 2GB and one 1GB window
instead.

The existing code has a few errors that need to be fixed in
order to support large RAM sizes. Fix those, and add a
comment to make it clearer.

Add a common setup function that determines the pci_region(s) based
on how much memory we have in the system.

* PCI Inbound window was setup incorrectly. The PCI address and system
address were swapped. The PCI address should be setting piwar/piwbear
and the system address should be setting pitar.
* Removed masking of addresses to allow for system address to support
system address & PCI address >32-bits
* Set PIWBEAR & POTEAR to allow for full 64-bit PCI addresses
* Respect the PCI_REGION_PREFETCH for inbound windows

pme_msg_det exists only on PCIe controllers only set it if we are a "bridge".

On the MPC85xx boards that have PCIe enable the PCIe errata fix.
(MPC8544DS, MPC8548CDS, MPC8568MDS).
