ece2678c62 avr32: Provide a way to deselect pins in the portmux
Currently, setting up the portmux is completely one-shot: Once a pin is
muxed, the portmux driver will complain loudly and refuse to do anything
if you try to set up the same pin again.

Sometimes, it may be necessary to change the configuration of a pin
after it has been set up initially. This patch adds a way to undo the
previous configuration, allowing the pin to be reconfigured.

7066412488 avr32: Allow fine-grained control over LCDC pins
This replaces the pin_config param with an u64 pin_mask in
at32_add_device_lcdc, allowing a board-maintainer to indivually select
specific lcdc pins.

b47eb4092f avr32: Clean up HMATRIX code
Introduce a few helper functions for HMATRIX configuration and clean up
the register definitions. Also add definitions for the HMATRIX master
and slave IDs on the AT32AP700x chips.

Also make the definitions in hmatrix.h available to board code by moving
it to <mach/hmatrix.h>

a8d902db22 avr32: Add MMIO address definitions for certain controllers
Hardcoded MMIO base addresses are used a few places throughout the
platform code. Move these into the chip-specific header file so that
adding support for new chips becomes a bit easier.

8f8a59c664 avr32: Introduce <mach/chip.h>
This file includes the appropriate chip-specific header with MMIO, IRQ
and GPIO definitions used by the platform code. It may also be used to
provide inline GPIO accessors for drivers that are willing to sacrifice
portability for faster bitbanging.

964d219b6a avr32: Introduce arch/avr32/mach-*/include/mach
Add arch/avr32/mach-*/include to include search path and copy all the
files from include/asm/arch there. The old files will be removed once
ARM does the same change and all common drivers are converted.
