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.
