  The FT32 simulator has character output, of course. This patch
adds character input, which lets the simulator run interactive
FT32 applications, e.g. language interpreters.

OK to apply?

sim/Changelog:

	* ft32/interp.c: reading from IO address 10000 gives
	character input.

should read like:
	* ft32/interp.c (cpu_mem_read): Call getchar when ea is 0x10000.
