arm/stm32h7: Include LSI helper when both consumers are enabled.

Browse source 
The filter expression for CONFIG_STM32_IWDG and CONFIG_STM32_RTC_LSICLOCK
returns "y y" when both are enabled. Comparing that result with "y"
omits stm32_lsi.c, leaving calls to stm32_rcc_enablelsi() unresolved.

Test for a nonempty result instead. Include the helper once when either
or both consumers are enabled, and omit it when neither is enabled.
This changes source selection only, without changing clock or watchdog
policy.
