Heiko Stuebner c2c70a7905 pinctrl: s3c24xx: use correct header for chained_irq functions
chained_irq_enter and chained_irq_exit moved to a real header
under linux/pinctrl instead of asm/.

Update the pinctrl driver to use the correct header and fix the
build error.

Heiko Stuebner af99a75074 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.
