Direct memory driver support for CoreSight Access Port(AP). Even though we emulate SWD (serial wire debug), we aren't actually using swd. Instead, we are using a direct memory access to get to the register set. This is similar in approach to other fast access native drivers such as am335xgpio drivers.
