Ricardo Ribalda Delgado a132892de6 amd/pi: Make BottomIo position configurable
Some PCI peripherals, such as FPGA accelerators, require a great amount
of memory mapped IO. This patch allows the user to select at build time
the bottom IO to leave enough space for such devices.

We cannot calculate this value at runtime because it has to be set
before the PCI devices are enumerated.

If PCI peripherals with big BARs are connected to the system
the bottom of the IO must be decreased to allocate such
devices.
Declare the beginning of the 128MB-aligned MMIO region. This
option is useful when PCI peripherals requesting large address
ranges are present.
