phy: dm816x: use __maybe_unused to hide pm functions
The dm816x USB PHY driver uses UNIVERSAL_DEV_PM_OPS to access its suspend/resume functions, which causes a warning about unused symbols when CONFIG_PM is disabled: drivers/phy/phy-dm816x-usb.c:121:12: error: 'dm816x_usb_phy_runtime_suspend' defined but not used [-Werror=unused-function] drivers/phy/phy-dm816x-usb.c:139:12: error: 'dm816x_usb_phy_runtime_resume' defined but not used [-Werror=unused-function] This adds __maybe_unused annotations to let the compiler know it can silently drop the function definition.
