openrisc: Declare do_signal function as static 

When compiling with W=1 enabling -Wmissing-prototypes the compiler
warns:

  arch/openrisc/kernel/signal.c:227:5: error: no previous prototype for 'do_signal' [-Werror=missing-prototypes]

Fix this by declaring the function a static as it is not used outside of
the scope of this file.
