powerpc: Fix booke user_disable_single_step()
On booke processors, gdb is seeing spurious SIGTRAPs when setting a
watchpoint.
user_disable_single_step() simply quits when the DAC is non-zero. It should
be clearing the DBCR0_IC and DBCR0_BT bits from the dbcr0 register and
TIF_SINGLESTEP from the thread flag.
