[PATCH v2 07/17] iwlwifi: mvm: protect D0i3 code behind CONFIG_PM

[Luca Coelho <luca@coelho.fi>]

From: Luca Coelho <luciano.coelho@intel.com>

Runtime PM can only be used if CONFIG_PM is set.  Move all the d0i3
code (which is essentially runtime PM) behind the CONFIG_PM flag.

This prevents undefined usage of some functions when CONFIG_PM is not
defined.
