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