The e500 MMU init code previously assumed KERNELBASE always equaled
PAGE_OFFSET and PHYSICAL_START was 0. This is useful for kdump
support as well as asymetric multicore.
For the initial kdump support the secondary kernel will run at 32M
but need access to all of memory so we bump the initial TLB up to
64M. This also matches with the forth coming ePAPR spec.

With that patch fixed.c now fully emulates MDIO bus, thus no need
to duplicate PHY layer functionality. That, in turn, drastically
simplifies the code, and drops down line count.
As an additional bonus, now there is no need to register MDIO bus
for each PHY, all emulated PHYs placed on the platform fixed MDIO bus.
There is also no more need to pre-allocate PHYs via .config option,
this is all now handled dynamically.

The current PCI code for Freescale 85xx/86xx was treating the virtual
P2P PCIe bridge as a transparent bridge. Rather than doing that fixup
the virtual P2P bridge by copying the resources from the PHB.
Also, fixup a bit of the code for dealing with resource_size_t being
64-bits and how we set ATMU registers for >4G.

The fixup code that handles the case for PowerMac's that leave bridge
windows open over an inaccessible region should only be applied to
memory resources (IORESOURCE_MEM). If not we can get it trying to fixup
IORESOURCE_IO on some systems since the other conditions that are used to
detect the case can easily match for IORESOURCE_IO.

There were several issues if a memreserve range existed and happened
to be in highmem:
* The bootmem allocator is only aware of lowmem so calling
reserve_bootmem with a highmem address would cause a BUG_ON
* All highmem pages were provided to the buddy allocator
Added a lmb_is_reserved() api that we now use to determine if a highem
page should continue to be PageReserved or provided to the buddy
allocator.
Also, we incorrectly reported the amount of pages reserved since all
highmem pages are initally marked reserved and we clear the
PageReserved flag as we "free" up the highmem pages.

xlate_iomm_address() really wants the ds_addr to pass to the HV, so store
that value (instead of the BAR number) when we allocate the device bars.
This is not a fast path, so we can look up the device_node property
there instead of using the bussubno field of the pci_dn.
The other user of iseries_ds_addr() was already scanning the device tree,
so looking up a property will not slow it down any more.
