[PATCH v4 2/5] clk: clk-gpio: update documentation for gpio-gate clock

[Heiko Stuebner]

The main documentation block seems to be from a time before the driver
handled sleeping and non-sleeping gpios and with that change it seems
updating the doc was overlooked. So do that now.

  * DOC: basic gpio gated clock which can be enabled and disabled
  *      with gpio output
  * Traits of this clock:
- * prepare - clk_(un)prepare only ensures parent is (un)prepared
- * enable - clk_enable and clk_disable are functional & control gpio
+ * prepare - clk_(un)prepare are functional and control a gpio that can sleep
+ * enable - clk_enable and clk_disable are functional & control
+ *          non-sleeping gpio
  * rate - inherits rate from parent.  No clk_set_rate support
  * parent - fixed parent.  No clk_set_parent support
