Subject: [PATCH] dt-bindings: interrupt-controller: arm: Drop redundant node name restrictions

Drop the redundant 'false' patterns so that allowed names
('msi-controller', 'gic-its', and 'interrupt-controller') work as intended

GICv3 binding currently disallows child nodes named 'gic-its@' and
'interrupt-controller@' via patternProperties set to 'false'. However,
these names are already permitted (though not preferred) by a subsequent
pattern that applies the correct schema.

Since the 'false' patterns take precedence, valid nodes such as
'gic-its@<addr>' and 'interrupt-controller@<addr>' fail dtbs_check with
"False schema does not allow" errors
