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.
