JTAG and SW debug support

The ARM JTAG debug port is embedded which enables debug using a standard JTAG

connection. The ARM serial wire debug port is also embedded which enables serial wire

debug to be connected to the CPU. The JTAG TMS and TCK pins are shared with the

SW_TDIO and SW_TCK respectively.

There are two mechanisms to select the debug mode. JTAG debug mode is selected by

setting the IO9 pin to zero. During reset, the SW debug mode is selected by default.
