Major changes to support 64-bit machines with Astro and Elroy chips.
This patch adds support for the C3700 workstation.
Changes include:
- Detect if the emulated CPU runs as 32-bit PA1.x or 64-bit PA2.x CPU
- Add support for Astro and Elroy chips:
* build interrupt routing table (IRT)
* add PCI irq to pci_device struct
- Enhance PCI bus scanning
* Add support for various PCI cards (serial, USB, graphics, ...)
- Change PCI I/O accessor functions:
* readX()/writeX() do byteswapping and take an ioremapped address
* __raw_readX()/__raw_writeX() don't byteswap and take an ioremapped address.
* gsc_*() don't byteswap and operate on physical addresses
