mfd: stm32-timers: Add support for interrupts
There are two types of STM32 timers that may have:
- a global interrupt line
- 4 dedicated interrupt lines.
Those interrupts are optional as defined in the dt-bindings. Enforce checks
on either one, four or no interrupts are provided with their names.
Optionally get them here, to be used by child devices.
