ARC: Make pt_regs regs unsigned

Browse Source 
KGDB fails to build after f51e2f1911 ("ARC: make sure instruction_pointer()
returns unsigned value")

The hack to force one specific reg to unsigned backfired. There's no
reason to keep the regs signed after all.

|  CC      arch/arc/kernel/kgdb.o
|../arch/arc/kernel/kgdb.c: In function 'kgdb_trap':
| ../arch/arc/kernel/kgdb.c:180:29: error: lvalue required as left operand of assignment
|   instruction_pointer(regs) -= BREAK_INSTR_SIZE;
