xtensa: implement task_user_regset_view
- define struct user_pt_regs in the arch/xtensa/include/uapi/asm/ptrace.h
with the same layout as xtensa_gregset_t; make xtensa_gregset_t a
typedef;
- define REGSET_GPR regset, implement register get and set functions;
- define task_user_regset_view function and expose REGSET_GPR.
