EDAC: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

EDAC, mpc85xx: Drop setting/clearing RFXE bit in HID1

On e500v1, read fault exception enable (RFXE) controls whether assertion
of core_fault_in causes a machine check interrupt. Assertion of
core_fault_in can result from uncorrectable data error, such as an L2
multi-bit ECC error. It can also occur from a system error if logic on
the integrated device signals a fault for nonfatal errors. RFXE bit is
cleared out of reset, and should be left clear for normal operation.
Assertion of core_fault_in does not cause a machine check.

RFXE is set specifically for RIO (Rapid IO) and PCI for book E to catch
the errors by machine check. With this bit set, the EDAC driver can't
get the interrupt in case of uncorrectable error. So this bit is cleared
in favor of EDAC. However, the benefit of catching such uncorrectable
error doesn't outweigh the other errors which may hang the system.
Besides, e500v2 has different errors masked by RFXE, and e500mc doesn't
support this bit. It is more reasonable to leave RFXE as is in the EDAC
driver, and leave the uncorrectable errors triggering machine check for
e500v1.

EDAC, mpc85xx: Make mpc85xx-pci-edac a platform device

Originally the mpc85xx-pci-edac driver bound directly to the PCI
controller node.

Commit

905e75c46dba ("powerpc/fsl-pci: Unify pci/pcie initialization code")

turned the PCI controller code into a platform device. Since we can't
have two drivers binding to the same device, the EDAC code was changed
to be called into as a library-style submodule. However, this doesn't
work if the EDAC driver is built as a module.

Commit

8d8fcba6d1ea ("EDAC: Rip out the edac_subsys reference counting")

exposed another problem with this approach -- mpc85xx_pci_err_probe()
was being called in the same early boot phase that the PCI controller
is initialized, rather than in the device_initcall phase that the EDAC
layer expects. This caused a crash on boot.

To fix this, the PCI controller code now creates a child platform device
specifically for EDAC, which the mpc85xx-pci-edac driver binds to.
