drivers: timer: stm32: Clean up related to STM32_LPTIM_CLOCK

Browse source 
Now that STM32_LPTIM_CLOCK choice symbol is defined from device tree,
remove the prompt which was defining it as a user selectable entry.

Remove the warning related to possible symbol misalignment with
device tree setting.
