[PATCH net-next 6/6] net: ipa: move IPA flags field

From: Alex Elder
Date: Wed Aug 04 2021 - 11:36:46 EST


The ipa->flags field is only ever used in "ipa_clock.c", related to
suspend/resume activity.

Move the definition of the ipa_flag enumerated type to "ipa_clock.c".
And move the flags field from the ipa structure and to the ipa_clock
structure. Rename the type and its values to include "power" or
"POWER" in the name.
