On MPC5200 the PCI target control register (PCITCR) @ MBAR + 0xD6C is
initialized with only bit 7 (Latrule disable) set. The 8-Bit write
combine timer (Bits 24..31) should be also set to a reasonable value
_greater zero_ (0x08 = default) since setting it to 0x00 leads to
_very poor_ performance as a PCI target since external burst won't be
possible at all.
Setting the WCT to 0x08 (cache-line size) leads to good overall perfomance.

Update MPC5200 drivers to also look for compatible properties in the
form "fsl,mpc5200-*" to better conform to open firmware generic names
recommended practice as published here:
http://www.openfirmware.org/1275/practice/gnames/gnamv14a.html
This patch should *not* break compatibility with older device trees
which do not use the 'fsl,' prefix. The drivers will still bind against
the older names also.

This patch moves a generic pci init code from lite5200
platform file to a common mpc52xx_setup_pci() routine
and adds additional compatibility property verification.

This adds to the 32 bits PCI code some flags, replacing the old
pci_assign_all_busses global, that allow us to control various
aspects of the PCI probing, such as whether to re-assign all
resources or not, or to not try to assign anything at all.
This also adds the flag x86 already has to avoid ISA alignment
on bridges that don't have ISA forwarding enabled (no legacy
devices on the top level bus) and sets it for PowerMacs.

Make the ppc32 pcibios_alloc_controller take a device node to match
the ppc64 prototypes and have it set arch_data.

There are times that we need to know which controller we are on to decide
how to exclude devices properly. We now pass the pci_controller that we
are going to use down to the pci_exclude_device function. This will
greatly simplify being able to exclude the PHBs in multiple controller
setups.

The hose->bus_offset is only used for PCI config cycles and the 52xx PCI
config code doesn't actually ever set bus_offset to a non-zero value.

The Freescale and Marvell PCI controllers dont require explicit setting for
type 1 config cycles. They handle producing them by implicitly looking at the
bus, devfn.
The TSI108 and 52xx don't use the generic PCI indirect code and thus don't
bother with set_cfg_type.
