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.

Changes since v1:
* Enable pullup on NWAIT
* Add missing include to portmux-pio.h
* Rename CONFIG_PIO2 -> CONFIG_PORTMUX_PIO to match docs
