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 15872 interrupts.

v4:
  - Use architectural maximum instead of practical maximum of 9,

v3:
  - Add Acked-by,

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

As with the clint - clears errors on the icicle dt, so fwiw:

Please refrain from posting encrypted messages to the mailing lists.

Apologies - not my usual mail client. It appears to have decided that
you (and Rob) should get it encrypted even though I had that disabled.
Actually doing so also would appear to be non trivial. I am hoping but
not expecting to have fixed it.
The mail to the list itself looks to be fine however.
