Subject: [PATCH v2 09/11] ARM: dts: stm32: List exti parent interrupts on stm32mp131

Stop using the table inside the EXTI driver and list in DT the
mapping between EXTI events and its parent interrupts.

By switching away from using the internal table, there is no need
anymore to use the specific compatible "st,stm32mp13-exti", which
was introduced to select the proper internal table.

Convert the driver's table for stm32mp131 to the DT property
interrupts-extended.
Switch the compatible string to the generic "st,stm32mp1-exti", in
place of the specific "st,stm32mp13-exti".

Older DT using compatible "st,stm32mp13-exti" will still work as
the driver remains backward compatible.
