The low power variant of the chipset introduces a completely
new interface to the GPIOs.
This is a 1KB region and so needs to be moved as well so it does
not conflict with other IO regions.
Also expose the gpio_get functions to ramstage and move the
prototypes to pch.h so they can be used for both GPIO interfaces.

The Haswell parts use a PCH code named Lynx Point (Series 8). Therefore,
the southbridge support is included as well. The basis for this code is
the Sandybridge code. Management Engine, IRQ routing, and ACPI still requires
more attention, but this is a good starting point.
This code partially gets up through the romstage just before training
memory on a Haswell reference board.
