Building without CONFIG_PM causes a harmless warning:
drivers/usb/musb/musb_core.c:2041:12: error: ‘musb_run_resume_work’ defined but
not used [-Werror=unused-function]
Removing the #ifdef around the PM code and instead marking the suspend/resume
functions as __maybe_unused will do the right thing without warning.
Fixes: ea2f35c01d5e ("usb: musb: Fix sleeping function called from invalid
context for hdrc glue")
