avr32: refactor the portmux/gpio code - Separate the portmux configuration functionality from the GPIO pin control API. - Separate the controller-specific code from the chip-specific code. - Allow "ganged" port configuration (multiple pins at once). - Add more flexibility to the "canned" peripheral select functions: - Allow using more than 23 address bits, more chip selects, as well as NAND- and CF-specific pins. - Make the MACB SPEED pin optional, and choose between MII/RMII using a parameter instead of an #ifdef. - Make it possible to use other MMC slots than slot 0, and support different MMC/SDCard data bus widths. - Use more reasonable pull-up defaults; floating pins may consume a lot of power. - Get rid of some custom portmux code from the mimc200 board code. The old gpio/portmux API couldn't really handle its requirements, but the new one can. - Add documentation. The end result is slightly smaller code for all boards. Which isn't really the point, but at least it isn't any larger. This has been verified on ATSTK1002 and ATNGW100. I'd appreciate if the board maintainers could help me test this on their boards. In particular, the mimc200 port has lost a lot of code, so I'm hoping Mark can help me out.
