pinctrl: stm32: check for IRQ MUX validity during alloc()
Considering the following irq_domain_ops call chain: - .alloc() is called when a clients calls platform_get_irq() or gpiod_to_irq() - .activate() is called next, when the clients calls request_threaded_irq() Check for the IRQ MUX conflict during the first stage (alloc instead of activate). This avoids to provide the client with an IRQ that can't be used.
