csky: Fix syscall_get_arguments() and syscall_set_arguments()
commit ed3bb007021b9bddb90afae28a19f08ed8890add upstream.
C-SKY syscall arguments are located in orig_a0,a1,a2,a3,regs[0],regs[1]
fields of struct pt_regs.
Due to an off-by-one bug and a bug in pointer arithmetic
syscall_get_arguments() was reading orig_a0,regs[1..5] fields instead.
Likewise, syscall_set_arguments() was writing orig_a0,regs[1..5] fields
instead.
