On stm32mp25, DIER (former IER) must only be modified when the lptimer
is enabled. On earlier SoCs, it must be only be modified when it is
disabled. There's also a new DIEROK flag, to ensure register access
has completed.
Add a new "set_evt" routine to be used on stm32mp25, called depending
on the version register, read by the MFD core (LPTIM_VERR).
