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.
