clk: add/modify debugfs support for clocks
Update clock debugfs to support the below functionalities.
- Allow enable/disable a clock.
- Allow set_rate on a clock.
- Display the list of enabled_clocks along with prepare_count,
enable_count and rate.
- Display the register contents of all the clocks which support
this clock operation.
