[gdbserver, aarch64] Use linux_{set,get}_pc_{64,32}bit

Browse Source 
We can use shared functions linux_{set,get}_pc_{64,32}bit in
linux-aarch64-low.c to write and read pc.

gdb/gdbserver:

2016-02-12  Yao Qi  <yao.qi@linaro.org>

	* linux-aarch64-low.c (aarch64_get_pc): Call linux_get_pc_64bit
	or linux_get_pc_32bit.
	(aarch64_set_pc): Call linux_set_pc_64bit or linux_set_pc_32bit.
