sb/intel/bd82x6x: Fix default IRQ mapping

The default mapping was probably copy-pasted from a random
board and disabled some interrupts (by implicitly clearing
some register bits).

We provide a new default mapping with some reasoning, that
tries to be most compatible (i.e. avoids to use PIRQ E-H
that are not shareable on some boards).

The following functions had their interrupt pin disabled
before:

o SATA 2 (explicitly, no board seems to enable the device)
  o PCIe Root Port #4, #6-#8 (probably by accident)
