pp_dpm_*clk nodes also could show the frequencies when a clock is in
'sleep' state. Add documentation related to that.

* pp_dpm_fclk interface is only available for Vega20 and later ASICs.
*
* Reading back the files will show you the available power levels within
- * the power state and the clock information for those levels.
+ * the power state and the clock information for those levels. If deep sleep is
+ * applied to a clock, the level will be denoted by a special level 'S:'
+ * E.g.,
+ * S: 19Mhz *
+ * 0: 615Mhz
+ * 1: 800Mhz
+ * 2: 888Mhz
+ * 3: 1000Mhz

* To manually adjust these states, first select manual using
* power_dpm_force_performance_level.
