First, I don't think the negative logic is as bad here because there is
no 'else' block which is far away. Second, I think we need a 'not'
anyhow because the condition is:
	'if not r8a779f0 then required interrupts'

Third, I still think we can fix it incrementally later if we want. The
new board has enough issues to take care of. For now, I'd rather
investigate those than YAML ;)
