Trying to do multiple operations on the same CBFS image at the same time
likely leads to data corruption. For this reason, add BSD advisory file
locking (flock()) to cbfstool (and ifittool which is using the same file
I/O library), so that only one process will operate on the same file at
the same time and the others will wait in line. This should help resolve
parallel build issues with the INTERMEDIATE target on certain platforms.
Unfortunately, some platforms use the INTERMEDIATE target to do a direct
dd into the CBFS image. This should generally be discouraged and future
platforms should aim to clearly deliminate regions that need to be
written directly by platform scripts with custom FMAP sections, so that
they can be written with `cbfstool write`. For the time being, update
the legacy platforms that do this with explicit calls to the `flock`
utility.

Additionally it also didn't take the swizzling into account.
Now that we know how AGESA programs the routing table we can correctly

We still route the PCI interrupts through the FCH IOAPIC. A follow up
will have the GNB IOAPIC handle the PCI interrupts.
There is still work to be done to fix the legacy PCI_IRQ register for
each PCI device. We can then remove the mainboard_pirq_data from each
