Update comments to target_can_use_hardware_watchpoint
The return value of target_can_use_hardware_watchpoint isn't well documented, so this patch is to update the comments to reflect the fact. This patch also removes a trailing ";" which is picked up from Pedro's patch https://sourceware.org/ml/gdb-patches/2015-04/msg00527.html gdb: 2015-04-17 Yao Qi <yao.qi@linaro.org> Pedro Alves <palves@redhat.com> * target.h (target_can_use_hardware_watchpoint): Update comments. Remove trailing ";".
