Subject: [PATCH 09/12] ARM: dts: stm32: Use exti interrupt-map on stm32mp131

Stop using the internal table of the exti driver and use the more
flexible interrupt-map feature in DT.
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 table to interrupt-map property.
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.
