Subject: [PATCH v3 3/5] dt-bindings: interrupt-controller: loongson,liointc: Fix dtbs_check for interrupt-names

The Loongson-2K0500/2K1000 CPUs have 64 interrupt sources as inputs, and
a route-mapped node handles up to 32 interrupt sources, so two liointc
nodes are defined in dts{i}.
Of course, we need to ensure that the routing outputs (intx) of the two
nodes cannot conflict.

For example, in Loongson-2K1000, 'int0' is typically used by the liointc0
node, then the liointc1 node can only use the outputs starting with
'int1'.

So "interrupt-names" should be defined by "pattern".

This fixes dtbs_check warning:
