the 'soc' node in the common .dtsi for MPC5121 has an '#interrupt-cells'
property although this node is not an interrupt controller
remove this erroneously placed property because starting with v3.13-rc1
lookup and resolution of 'interrupts' specs for peripherals gets misled,
emits 'no irq domain found' WARN() messages and breaks the boot process
irq: no irq domain found for /soc@80000000 !
