the mini-uart clock is referenced off the main VPU clock

if you set enable_uart=1 in config.txt, then the VPU clock just stops doing powersaving things, and will not change freq, because there is no standard way to handle things with 2 kernels fighting over the hw

the PL011 uart has its own dedicated divisor and wont change during power savings
