ARM: arm920/s3c24xx: IRQ demulitplexer callback
This patch adds a IRQ demultiplexer callback to the arm920 cpu core code,
plus a stub implementation of it for the S3C2410.
The purpose is to allow arm920t implementations such as the s3c24x0 to
implement interrupt handlers in u-boot without having to touch core
arm920t code.
