[PATCH v6 10/16] dmaengine: tegra-apb: Remove assumptions about unavailable runtime PM

[Dmitry Osipenko]

The runtime PM is always available on all Tegra SoCs since the commit
40b2bb1b132a ("ARM: tegra: enforce PM requirement"), so there is no
need to handle the case of unavailable RPM in the code anymore.
