This fixes an oops on unbind / module unload (on the musb omap2430
platform).

musb_remove function now calls musb_platform_exit before disabling
runtime pm.

Thank you. Is there any chance that this patch and the vbus patch could
end up in the 4.16-rc series? I was waiting for another rc to see if the
vbus patch would land, but it didn't land with 4.16-rc5.

Cheers,
Merlijn

Those two patches are already in the upstream tree, hopefully they will
be in the v4.16-rc.
