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> Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
