Currently, enabling wakeup for the IPA device doesn't occur until the setup phase of initialization (in ipa_power_setup()). There is no need to delay doing that, however. We can conveniently do it during the config phase, in ipa_interrupt_config(), where we enable power management wakeup mode for the IPA interrupt. Moving the device_init_wakeup() out of ipa_power_setup() leaves that function empty, so it can just be eliminated. Similarly, rearrange all of the matching inverse calls, disabling device wakeup in ipa_interrupt_deconfig() and removing that function as well.
