[AVR32] Clean up cpu identification and add features bitmap
Clean up the cpu identification code, using definitions from <asm/sysreg.h> instead of hardcoded constants. Also, add a features bitmap to struct avr32_cpuinfo to allow other code to make decisions based upon what the running cpu is actually capable of.
