[ Upstream commit 71c4f6027da75c6c1fd92e05b63108a09ec2b109 ]
N900 legacy user space apps need the board name in /proc/cpuinfo to work properly for the Hardware entry.
For other boards this should not be an issues and they can use the generic Hardware entry.
Let's fix the issue by adding a custom DT_MACHINE_START for n900.
