driver: timer: stm32_lptim: only set LSE drive if supported

Browse source 
Not all platforms support setting the LSE driving capability, causing
the build to fail for platform such as the STM32L072 if compiled with
CONFIG_STM32_LPTIM_CLOCK_LSE=y.

Adding an #ifdef guard around the call to skip it if not defined in the
HAL.
