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. Signed-off-by: Erwan Gouriou <erwan.gouriou@st.com>

For LPTIM configuration, a specific tick freq is advised
|
|
depending on LPTIM input clock:
|
|
- LSI(32KHz): 4000 ticks/sec
|
|
- LSE(32678): 4096 ticks/sec
|
|
To prevent misconfigurations, a dedicated check is implemented
|
|
in the driver.
|
|
This options allows to override this check
