ASoC: tegra20: spdif: Remove handing of disabled runtime PM

Runtime PM is always available on Tegra since commit 40b2bb1b
("ARM: tegra: enforce PM requirement"), hence there is no need to
handle the case of a disabled RPM by Tegra drivers. Remove handing
of a disabled runtime PM from Tegra20 SPDIF driver.
