* The CPU PLL is actually NP clock, with P being /1, /2 or /4. However
* P should only be used for output frequencies lower than 288 MHz.
*
* For now we can just model it as a multiplier clock, and force P to /1.
*
* The M factor is present in the register's description, but not in the
* frequency formula, and it's documented as "M is only used for backdoor
* testing", so it's not modelled and then force to 0.
