Stefan Kerkmann 1d2a57a9e1 Remove unsuitable clock configurations from init code
Only 48MHz, 72MHz, 96MHz and 120 MHz system clocks derived from an
external crystal are suitable for the usb peripheral, as the internal
oscillator is not stable enough. Also the usb-prescaler only supports
division by 1 (48MHZ), 1.5(72MHz), 2(96MHz) and 2.5(120Mhz).
120Mhz is also out of spec and not added here.
