To improve human readability and enable automatic validation, the tuples
in "interrupts-extended" properties should be grouped using angle
brackets.  As the DT bindings lack an upper bound on the number of
interrupts, thus assuming one, proper grouping is currently flagged as
an error.

Fix this by adding the missing "maxItems", limiting it to 10 interrupts
(two interrupts for a system management core, and two interrupts per
core for other cores), which should be sufficient for now.

Group the tuples in the example.

Cfr. Jessica's comment on my PLIC patch:

The maximum supported by the CLINT memory map is 8192.
Device-specific limits would be 4 for k210 and jh7100, and 10 for
fu540.
