The MHU secure interrupt exists physically but is missing in the DT node.

Specify the interrupt in DT node to fix a warning on Arm Juno board:
   mhu@2b1f0000: interrupts: [[0, 36, 4], [0, 35, 4]] is too short

It fails to apply on v5.18-rc1 or v5.19. Can you please rebase and resend ?

Sorry I meant v5.19-rc1 or v5.19 as my -next branch is based on the former.
IIUC the interrupt-names are dropped couple of release back as it was not
in the binding.
