MSP430: sim: Increase main memory region size

The area between 0xFF00 and 0xFFC0 is unallocated in the simulator
memory map, so extend the main memory region up to 0xFFC0 to allow the
simulator to make use of the extra 192 bytes of space.

sim/msp430/ChangeLog:

	* msp430-sim.c (sim_open): Increase the size of the main memory region
	to 0xFAC0.
