For boards that need to do large contiguous allocations it of course
makes sense to have this number bumped up. Most boards however do not
require this, so we always stick with a conservative default.
What happened here is that you tried to alloc a large contiguous block
that exceeded the max order and got an -ENOMEM, so we don't have any
option but to bump the max order for this case.
