Stacey Sheldon 59cb489e01 usb: clean up pios hooks into stm32 usb_core
Reduced scope of many variables since they were being
exposed unnecessarily.

Renamed pios_usb_hid_prop code to pios_usbhook to reflect
the fact that it implements all of the callout functions
that are hooked into the stm32 usb library.
