clk: Add support for list_rates ops for clocks
Add support for clocks debugfs to be able to display
- rates_max which indicates the frequency to voltage mapping of a clock.
- list_rates, the list of clock frequencies supported by root clocks.
- Also display the rate_max associated with enabled clocks list.
