Raph Francois / LPC4088-USBHost

Added to LPC4088-USBHost the USBHostMidi class. Plugin an usb midi interface to the usb host of lpc4088 allows to send midi event to the midi interface. For the moment I can not be able to get event from the interface by using the attacheNoteOn or other triggers...

Dependencies:   FATFileSystem mbed-rtos
