ASoC: tegra30: ahub: Correct suspend-resume callbacks
Tegra30 AHUB driver always syncs hardware state on a runtime PM resume, hence there is no needed to re-sync the state on system resume. Replace the suspend-resume callbacks with a generic helpers which ensure that AHUB is suspended using RPM callbacks across system suspend-resume.
