[AVR32] Clean up OCD register usage
Generate a new set of OCD register definitions in asm/ocd.h and rename __mfdr() and __mtdr() to ocd_read() and ocd_write() respectively. The bitfield definitions are a lot more complete now, and they are entirely based on bit numbers, not masks. This is because OCD registers are frequently accessed from assembly code, where bit numbers are a lot more useful (can be fed directly to sbr, bfins, etc.) Bitfields that consist of more than one bit have two definitions: _START, which indicates the number of the first bit, and _SIZE, which indicates the number of bits. These directly correspond to the parameters taken by the bfextu, bfexts and bfins instructions. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
