powerpc/watchpoint: Add hw_len wherever missing
There are couple of places where we set len but not hw_len. For ptrace/perf watchpoints, when CONFIG_HAVE_HW_BREAKPOINT=Y, hw_len will be calculated and set internally while parsing watchpoint. But when CONFIG_HAVE_HW_BREAKPOINT=N, we need to manually set 'hw_len'. Similarly for xmon as well, hw_len needs to be set directly.
