Subject[PATCH v2 1/2] dt-bindings: interrupt-controller: sifive,plic: Fix number of interrupts
Date
The number of interrupts lacks an upper bound, thus assuming one,
causing properly grouped "interrupts-extended" properties to be flagged
as an error by "make dtbs_check".

Fix this by adding the missing "maxItems". As the architectural maximum
is 15872 interrupts, using that as the limit would be unpractical.
Hence limit it to 9 interrupts (one interrupt for a system management
core, and two interrupts per core for other cores). This should be
sufficient for now, and the limit can always be increased when the need
arises.
