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)
PIRQs used before this change: A-D, F and H. After this
change: A-D.
