net: ipa: call device_init_wakeup() earlier
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.
