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.
