Matt Hsu <matt@0xlab.org> cortex_a8_exec_opcode is writing the ARM instruction into
the ITR register but it will only be executed when the DSCR[13]
bit is set. The documentation is a bit weird as it classifies
the DSCR as read-only but the pseudo code is writing to it as
well. This is working on a beagleboard.
