[PATCH 1/2] dt-bindings: timer: econet: Update EN751627 for multi-IRQ

[Caleb James DeLisle]

>From conception, this driver supported EN751627 as it is the same
hardware that is used in EN751221. However, it was expected that
EN751627 would use a percpu IRQ as does EN751221, this is how it
works in vendor code. However upon finding that the "mti,gic" intc
works on EN751627 with no modification - but it provides a unique
interrupt per-timer, it is deemed best to make this driver use
multiple IRQs when on the EN751627 platform.
