Fabien Dessenne f3c3b0f1fa irqchip/stm32: Don't clear rising/falling config registers at init ...

[ Upstream commit 0dda09666f ]

Falling and rising configuration and status registers are not banked.
As they are shared with M4 co-processor, they should not be cleared
at probe time, else M4 co-processor configuration will be lost.
