pl050: split pl050_update_irq() into separate pl050_set_irq() and pl050_update_irq() functions
This will soon allow pl050_set_irq() to be used as a GPIO input function. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Acked-by: Helge Deller <deller@gmx.de> Message-Id: <20220624134109.881989-16-mark.cave-ayland@ilande.co.uk>
