[committed] MSP430: sim: Increase main memory region size

[Jozef Lawrynowicz <jozef.l@mittosystems.com>]

[-- Attachment #1: Type: text/plain, Size: 283 bytes --]

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.

Successfully regtested with the GCC DejaGNU C and C++ testsuites.

Committed as obvious.
