Teach SH-Mobile ARM how to make use of the shared SH clock framework. This commit is one atomic switch that dumps the local hackery and instead links in the shared clock framework code in drivers/sh. A few local functions are kept in clock.c. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
