hw/misc/bcm2835_cprman: implement PLLs behaviour
The CPRMAN PLLs generate a clock based on a prescaler, a multiplier and a divider. The prescaler doubles the parent (xosc) frequency, then the multiplier/divider are applied. The multiplier has an integer and a fractional part. This commit also implements the CPRMAN CM_LOCK register. This register reports which PLL is currently locked. We consider a PLL has being locked as soon as it is enabled (on real hardware, there is a delay after turning a PLL on, for it to stabilize).
