mb/gigabyte/ga-b75m-d3h: add ACPI definitions for legacy PCI slots
All variants of ga-b75m-d3h lack ACPI definitions for legacy PCI
slots, which causes IRQ issue if it gets legacy PCI card installed.
The missing definitions (mainly Interrupt Routing Table) are added to
fix that.
NOTE: The added definitions are actually for ga-b75-d3v, but since
they form superset of definitions needed by ga-b75m-d3{h,v}, they can
be applied to all three existing variants with suitable preprocessor
instructions.
