The function of_clk_add_provider() has been deprecated, so use its
suggested replacement of_clk_add_hw_provider() instead.

Since of_clk_add_hw_provider() can fail, like of_clk_add_provider(),
check its return value and do the error handling.

The indentation of the init function parameters has been aligned
to match open parenthesis, as suggested by checkpatch, and the __init
macro moved before the function name, as specified in init.h.
