irqchip/stm32: Add stm32mp1 support with hierarchy domain
Exti controller has been differently integrated on stm32mp1 SoC.
A parent irq has only one external interrupt. A hierachy domain could
be used. Handlers are call by parent, each parent interrupt could be
masked and unmasked according to the needs.
