mb/gigabyte/ga-b75m-d3h: enable superspeed ports for all variants
Unlike other x7x boards, the ga-b75m-d3h lacks definitions to wire SuperSpeed-capable ports to XHCI in its device tree, causing these ports being wired to the second EHCI, and only working as USB 2.0 ports.
This change will add them.
Tested on my ga-b75-d3v board.
