The interrupt controller lives at I/O 0x4d0/0x4d1.

The interrupt controller lives at I/O 0x4d0/0x4d1.
However on these platforms we were causing a resource conflict by
letting the resource allocator start allocations at 0x400.
Change the constraints to start at 0x1000 so we avoid allocating over
LPT ports (0x778-0x77f), PCI (0xcf8-0xcff) and some other fixed
resources that might live down there (smbus base, acpi base,...)
