target-arm: Support coprocessor registers which do I/O
Add an ARM_CP_IO flag which an ARMCPRegInfo definition can use to
indicate that the register's implementation does I/O and thus
its accesses need to be surrounded by gen_io_start()/gen_io_end()
in order for icount to work. Most notably, cp registers which
implement clocks or timers need this.
