The usage of in_interrupt() in drivers is phased out for various reasons.

Various comments use !in_interrupt() to describe calling context for probe()
and remove() functions. That's wrong because the calling context has to be
preemptible task context, which is not what !in_interrupt() describes.

Cleanup the comments. While at it add the missing kernel doc argument
descriptors and make usb_hcd_msp_remove() static.
