PM: clk: make pm_clk_add_notifier() take a const pointer

Browse Source 
The driver core wants to work with const struct bus_type, so there's no
reason that pm_clk_add_notifier() should not also do the same thing,
considering that it just passes the pointer off to the driver core which
is expecting a const *.
