dt-bindings: mailbox: arm,mhu: Make secure interrupt optional

Browse Source 
The secure interrupt is only useful to secure world, therefore for NS
users it shouldn't be required. Make it optional.

This fixes a warning on Arm Juno board:

mhu@2b1f0000: interrupts: [[0, 36, 4], [0, 35, 4]] is too short
