mips: dbau1x00: Remove this board
This platform has been marked as orphan since June of 2016 and should
have been removed some time ago. Do so now.

This makes it possible -to test new bootloaders without thrashing the YAMON -boot loader delivered with board. - -NOTE! When you switch between the two boot flashes, the -base addresses will be swapped. -Have this in mind when you compile u-boot.
