hw/timer/imx_epit: remove explicit fields cnt and freq
The CNT register is a read-only register. There is no need to store it's value, it can be calculated on demand. The calculated frequency is needed temporarily only.
Note that this is a migration compatibility break for all boards types that use the EPIT peripheral.

hw/timer/stellaris-gptm: Use Clock input instead of system_clock_scale
The stellaris-gptm timer currently uses system_clock_scale for one of its timer modes where the timer runs at the CPU clock rat
hw/timer/stellaris-gptm: Use Clock input instead of system_clock_scale
The stellaris-gptm timer currently uses system_clock_scale for one of its timer modes where the timer runs at the CPU clock rate. Make it use a Clock input instead.
We don't try to make the timer handle changes in the clock frequency while the downcounter is running. This is not a change in behaviour from the previous system_clock_scale implementation -- we will pick up the new frequency only when the downcounter hits zero. Handling dynamic clock changes when the counter is running would require state that the current gptm implementation doesn't have.
