Subject[PATCH v7 07/22] h8300: define remaining syscall_get_* functions
syscall_get_* functions are required to be implemented on all
architectures in order to extend the generic ptrace API with
PTRACE_GET_SYSCALL_INFO request.

This adds remaining 3 syscall_get_* functions as documented in
asm-generic/syscall.h: syscall_get_error, syscall_get_return_value,
and syscall_get_arch.
