net: ipa: rename ipa_clock_* symbols

Rename a number of functions to clarify that there is no longer a
notion of an "IPA clock," but rather that the functions are more
generally related to IPA power management.

  ipa_clock_enable() -> ipa_power_enable()
  ipa_clock_disable() -> ipa_power_disable()
  ipa_clock_rate() -> ipa_core_clock_rate()
  ipa_clock_init() -> ipa_power_init()
  ipa_clock_exit() -> ipa_power_exit()

Rename the ipa_clock structure to be ipa_power.  Rename all
variables and fields using that structure type "power" rather
than "clock".

Rename the ipa_clock_data structure to be ipa_power_data, and more
broadly, just substitute "power" for "clock" in places that
previously represented things related to the "IPA clock".

Update comments throughout.

- * The "IPA Clock" manages both the IPA core clock and the interconnects
- * (buses) the IPA depends on as a single logical entity.  A reference count
- * is incremented by "get" operations and decremented by "put" operations.
- * Transitions of that count from 0 to 1 result in the clock and interconnects
- * being enabled, and transitions of the count from 1 to 0 cause them to be
- * disabled.  We currently operate the core clock at a fixed clock rate, and
- * all buses at a fixed average and peak bandwidth.  As more advanced IPA
- * features are enabled, we can make better use of clock and bus scaling.
+ * The IPA hardware is enabled when the IPA core clock and all the
+ * interconnects (buses) it depends on are enabled.  Runtime power
+ * management is used to determine whether the core clock and
+ * interconnects are enabled, and if not in use to be suspended
+ * automatically.
  *
- * An IPA clock reference must be held for any access to IPA hardware.
+ * The core clock currently runs at a fixed clock rate when enabled,
+ * an all interconnects use a fixed average and peak bandwidth.
