This struct contains information about how the sound chip is hooked up
on the board, so it needs to be defined in a place where the platform
code can easily find it. Since it's not arch specific, it doesn't
belong under <asm/...> so <linux/spi/...> seems like a logical choice.

This patch shows how it's meant to be used:
