net: ipa: disable clock in suspend
Disable the IPA clock rather than dropping a reference to it in the
system suspend callback. This forces the suspend to occur without
affecting existing references.
Similarly, enable the clock rather than taking a reference in
ipa_resume(), forcing a resume without changing the reference count.
