sh: Rework SuperH Mobile sleep mode code
Rework the SuperH Mobile sleep code from including board specific code to allowing each board to provide pre/post code snippets. These snippets should contain sdram management code to enter and leave self-refresh. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
