net: ipa: get rid of extra clock reference
Suspending the IPA hardware is now managed by the runtime PM core code. The ->runtime_idle callback returns a non-zero value, so it will never suspend except when forced. As a result, there's no need to take an extra "do not suspend" clock reference. Signed-off-by: NAlex Elder <elder@linaro.org> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
