haswell: move to mp_init library

The mp_init library was based off of haswell code, but baytrail
was the first chipset to take advantage of it. Move haswell over
to using it so that the code duplication can be removed.

baytrail: interrupt routing support

This provides the initial support for interrupt routing
in bay trail. It includes both acpi changes and board changes
to ensure the interdependencies are met with the current ASL
code. The PIRQ routing is handled by the mainboard exporting
an irqroute.h header that describes the per device and PIRQ
PCI settings.

There are still a lot of ACPI errors in the kernel with this
change, though.

baytrail: fix up FADT

The FADT for baytrail had incorrect offsets leading to
the kernel spewing a huge mess of ACPI errors. Fix these offsets
to be initialized in the chipset code.
