[PATCH 02/14] pinctrl: stm32: Manage irq affinity settings

[Antonio Borneo <antonio.borneo@xxxxxxxxxxx>]

From: Cheick Traore <cheick.traore@xxxxxxxxxxx>

Trying to set the affinity of the interrupts associated to stm32
pinctrl results in a write error.

Fill struct irq_chip::irq_set_affinity to use the default helper
function.
