the 'soc' node in the MPC5125 "tower" board .dts 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
(tries to use the 'soc' as the interrupt parent which fails), emits
'no irq domain found' WARN() messages and breaks the boot process
[ best viewed with 'git diff -U5' to have DT node names in the context ]

note that this is not a resend of the previous MPC5121 fix, but instead
is a fix for MPC5125 along the same lines of the MPC5121 fix
