Share enum arm_breakpoint_kinds

This patch shares "enum arm_breakpoint_kinds", and use ARM_BP_KIND_THUMB2
in GDB.

gdb:

2016-10-10  Yao Qi  <yao.qi@linaro.org>

	* arch/arm.h (enum arm_breakpoint_kinds): New.
	* arm-tdep.c (arm_remote_breakpoint_from_pc): Use
	ARM_BP_KIND_THUMB2.

gdb/gdbserver:

2016-10-10  Yao Qi  <yao.qi@linaro.org>

	* linux-aarch32-low.c (enum arm_breakpoint_kinds): Remove.
