Keep a pointer to the corresponding s3c_irq_data struct as irq_chip_data.
This removes the need to fetch the intc struct from the irq_domains
host_data, thus making it independent of the underlying irq_domain
structure.
Also keep the real register offset of the interrupt in the s3c_irq_data
struct to make it independent of the hwirq structure in the irq_domain

For dt-enabled machines we want to use a big irq_domain over all controllers
and therefore need to access not only the main controllers but the
sub-controller as well.

Enables post-init setting of the desired typehandler for the interrupt.

The list in used was from the s3c2450, a close cousin of the s3c2416.
As it's not possible to distinguish between the s3c2416 and s3c2450
the additional interrupts of the s3c2450 will only be available thru
devicetree later.

Might be confusing for people to read the code without having the
datasheet nearby.

This move is necessary to make use of the irqchip infrastructure
for the following devicetree support for s3c24xx architectures.
