Add code to allow boards registering self-contained functions for going to/from self-refresh. At this point the board code is unused. When all supported boards have been converted then the new sleep code will make use of these functions. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
