The default interrupt control for GPIO pins within stoneyridge is for
edge triggered, high. However, sometimes these need to change, or maybe
the interrupt needs to be reported or delivered. This was the case of
platform grunt, where the interrupt related bits were being changed
afterwards. Ideally all the bits should be programmed through the same
procedure. Create several PAD_INT definitions (for general configuration,
for trigger configuration and for interrupt type configuration) and change
function sb_program_gpios() to accept the output from PAD_INT_XX and
program all the necessary bits while keeping compatibility with other
PAD_XX definitions.

This board was used a test target for the x4x DDR3 raminit patches and
has an easy to access DIP8 socket.
What is tested and works:
* S3 resume
* PEG, PCI, USB, SATA
* Sound
* Ethernet
* Native graphic init (textmode and linear fb) on the VGA output
* Passing memtest86+ with 2 2Rx8 4G dimms
* PS2 Keyboard
* Flashing coreboot internally from vendor BIOS.
What does not work:
* Running dram at 533 MHz (limited at 400MHz currently)

This change moves PL2 override to variant_devtree_update for two reasons:
1. This function was added to basically override devtree settings in
variant specific code. So, it would be a good idea to perform all the
overrides in a single place.
2. Adding a device for performing nami_enable would require changes to
devicetree and special handling for calling this device enable. Thus,
nami_enable was never getting called.

This creates a pin-route matrix first and then generates the ACPI
entries based on that. This approach has the advantage of being
simpler (no need for checks on double entries) and requiring less
access to the pci config space.
A few thing that are also fixed:
* Don't declare DEFAULT_RCBA redundantly.
* Only loop over PCI devices on bus 0
* Add a license header to rcba_pirq.c
* Remove inappropriate use of typedefs
* Fix the pin field: needs to be a byte
* Fix the source field: it should either be a byte or a path
(according to Advanced Configuration and Power Interface Specification

To access the hardware, "simple device" handles are used. These

DEVTREE_EARLY in the code.
This file is about the latter and its name reflects that the

Tested with GRUB 2.02 as a payload, booting Arch Linux with
latest kernel. This code is based on the output of autoport
as well as existing ga-b75m-d3h and ga-b75m-d3v mainboards.
Working:
- Serial port I/O
- S3 suspend/resume (broken with SeaBIOS 1.11.1)
- USB ports and headers
- Gigabit Ethernet
- Integrated graphics (libgfxinit)
- PCIe x16 graphics
- PCIe x1
- SATA controller
- Hardware Monitor
- Fan Control (fancontrol on linux works well)
- Native raminit (4+4GB, 4+2GB, 2+2GB, DDR3-1333)
- Native graphics init with libgfxinit
- flashrom, using the internal programmer. Tested with coreboot,
as well as with the vendor firmware. Backup chip is untested.
- NVRAM settings. Only `gfx_uma_size` and `debug_level` have been
tested with values different from the default.
Untested:
- VGA BIOS for integrated graphics init
- DVI port. It can detect a "fake" display, that is, an
EEPROM connected to the DVI port.
- PS/2 ports
- Audio: Only rear output (green) has been tested.
- EHCI debug.
- Parallel port
- Non-Linux OSes
- ACPI thermal zone and fan control (probably not working)
Not working:
- SATA devices with Tianocore (payload issue)
- PCIe to PCI bridge. It seems to be poorly supported on Linux,
it lacks a public datasheet and vendor BIOS behaves in the
same way: The bridge and the devices behind it appear, but
drivers fail to find devices attached to the bridge.
