Subject: [PATCH 1/6] usb: host: unhide suspend/resume declarations

There is no need to hide function declarations, and making
these visible to the SoC specific host drivers lets us
use __maybe_unused and IS_ENABLED() checks to control
their use, rather than having to use #ifdef to hide all
callers.
