This serves two main purposes: - change the CPU clock via devicetree nodes - provide the APB frequency to device drivers via the clock driver interface Theoretically this could also support choosing between the available clock sources, but right now we only support LPOSC0 going into PLL0, going into AHB. Turning the PLL back off is also not supported since the only current use case is to set the PLL frequency, turn it on, and switch the AHB over to it.

Enable support for hardware clock controller. Such hardware can
|
|
provide clock for other subsystem, and thus can be also used for
|
|
power efficiency by controlling their clock. Note that this has
|
|
nothing to do with RTC.
