pinctrl: Add pinctrl-s3c24xx driver
The s3c24xx pins follow a similar pattern as the other Samsung SoCs and can therefore reuse the already introduced infrastructure. The s3c24xx SoCs have one design oddity in that the first 4 external interrupts do not reside in the eint pending register but in the main interrupt controller instead. We solve this by forwarding the external interrupt from the main controller into the irq domain of the pin bank. The masking/acking of these interrupts is handled in the same way. Furthermore the S3C2412/2413 SoCs contain another oddity in that they keep the same 4 eints in the main interrupt controller and eintpend register and requiring ack operations to happen in both. This is solved by using different compatible properties for the wakeup eint node which set a property accordingly.
