hw/arm/raspi: add a skeleton implementation of the CPRMAN The BCM2835 CPRMAN is the clock manager of the SoC. It is composed of a main oscillator, and several sub-components (PLLs, multiplexers, ...) to generate the BCM2835 clock tree. This commit adds a skeleton of the CPRMAN, with a dummy register read/write implementation. It embeds the main oscillator (xosc) from which all the clocks will be derived.

hw/misc/bcm2835_cprman: add a PLL skeleton implementation There are 5 PLLs in the CPRMAN, namely PLL A, C, D, H and B. All of them take the xosc clock as input and produce a new clock. This commit adds a skeleton implementation for the PLLs as sub-devices of the CPRMAN. The PLLs are instantiated and connected internally to the main oscillator. Each PLL has 6 registers : CM, A2W_CTRL, A2W_ANA[0,1,2,3], A2W_FRAC. A write to any of them triggers a call to the (not yet implemented) pll_update function. If the main oscillator changes frequency, an update is also triggered.

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).
