[PATCH v1] clkdev: prevent potential memory leak when used in modules

[Andy Shevchenko]

Since clk_register_clkdev() is exported for modules the caller should get a
pointer to the allocated resources. Otherwise the memory leak is guaranteed on
the ->remove() stage.

The patch changes the prototype of the clk_register_clkdev() to return pointer
to the allocated resources. The caller should take care of the returned
variable and free allocated resources when needed. Together with the main
change the users are updated too.

The patch compile tested on x86, thus requires to be tested on touched
architectures.
