Subject: [PATCH v4 1/2] dt-bindings: timer: sifive,clint: Fix number of interrupts

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", using the architectural
maximum of 4095 interrupts.

---
v4:
  - Use architectural maximum instead of practical maximum of 10,

v3:
  - Add Acked-by,

v2:
  - Split in two patches,
  - Improve patch description and document limit rationale.
