ALSA: hda/tegra: avoid build error without CONFIG_PM

Browse Source 
The #ifdef protection around the PM functions is wrong, leading to
a failed reference in some configurations:

sound/pci/hda/hda_tegra.c: In function 'hda_tegra_runtime_suspend':
sound/pci/hda/hda_tegra.c:273:2: error: implicit declaration of function 'hda_tegra_disable_clocks'; did you mean 'hda_tegra_enable_clocks'? [-Werror=implicit-function-declaration]

Better remove the #ifdefs entirely and rely on the compiler silently
dropping unused functions marked __maybe_unused.

Fixes: 707e0759f2 ("ALSA: hda/tegra: implement runtime suspend/resume")
