[PATCH] sh: clkfw: Moved the .init callback in the clk_regsiter

[Francesco VIRLINZI <francesco.virlinzi@st.com>]

This patch moves the .init callback in the clk_register function.
Moreover not the .init callback return a value:
 - zero means the initialization is ok and the clock can be registered.
 - any value not zero means there is a problem in the initialization and
   the clkfw rejects the clock registration
