* VCO output frequency = VCO input frequency × PLLN, 192 <= PLLN <= 432
* PLL output clock frequency = VCO frequency / PLLP, PLLP = 2, 4, 6, or 8
* USB OTG FS clock frequency = VCO frequency / PLLQ, 2 <= PLLQ <= 15
*
* There is no config for 100 MHz and 48 MHz for usb,

* pointer to configuration data read from a file or serial FLASH,
* or whatever you would like to do with it. Every implementation
* should accept zero/NULL as a default configuration.
*
* Returned Value:
* Zero (OK) is returned on success; a negated errno value is returned on
* any failure to indicate the nature of the failure.
