Subject: [PATCH] clk: shmobile: check for failure

We were not checking the return from devm_add_action() which can fail.
Start using the helper devm_add_action_or_reset() and return directly
as we know that the cleanup has been done by this helper.

I think this will go throuh clk tree, so this doesnot have to wait as
devm_add_action_or_reset() is already in clk tree.
