pinctrl: sh-pfc: Do not use platform_get_irq() to count interrupts
As platform_get_irq() now prints an error when the interrupt does not exist, counting interrupts by looping until failure causes the printing of scary messages like: sh-pfc e6060000.pin-controller: IRQ index 0 not found Fix this by using the platform_irq_count() helper instead.
