usb: musb: remove hand-crafted id handling
This replaced the handcrafted id handling by the PLATFORM_DEVID_AUTO value which should do the same thing. This patch probably also fixes ux500 because I did not find the "musbid" variable to remove. And we close a tiny-unlikely race window becuase the old code gave the id back before device was destroyed in the remove case.
