phy: tegra: xusb: mark PM functions as __maybe_unused 

When these are not referenced, gcc prints a harmless warning:

drivers/phy/tegra/xusb.c:1286:12: error: 'tegra_xusb_padctl_resume_noirq' defined but not used [-Werror=unused-function]
 1286 | static int tegra_xusb_padctl_resume_noirq(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/phy/tegra/xusb.c:1276:12: error: 'tegra_xusb_padctl_suspend_noirq' defined but not used [-Werror=unused-function]
 1276 | static int tegra_xusb_padctl_suspend_noirq(struct device *dev)
      |            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
