[U-Boot] [RFC PATCH] MIPS: incaip: move board specific code out of generic code

[Daniel Schwierzeck]

This is required to switch MIPS platform to generic board.

Wolfgang, I would rather remove this board. It is obviously dead and no one ever
cared about it since you have added it. The code does not conform to current
coding style. Also it needs a lot of cleanup if we switch to driver model 
eventually.
