nb/sandybridge,sb/bd82x6x: Configure USB from southbridge devicetree

Transfer all USB responsibilities to southbridge/intel/bd82x6x,
using one set of USB port configuration supplied by mainboards
in the southbridge section of their devicetree.

For MRC raminit, export southbridge_fill_pei_data() as a hook for
southbridge code to implement. With new code via this hook, bd82x6x
fills pei_data based on this one set of USB port config.

For native raminit, early_usb_init() now goes directly to the devicetree
and no longer get passed an address to it.

TEST=abuild passes for all affected boards. All USB ports still work
on asus/p8x7x-series/v/p8z77-m.
