bc75059422 powerpc/512x: dts: add MPC5125 clock specs 
add clock related specs to the MPC5125 "tower" board DTS
- add clock providers (crystal/oscillator, clock control module)
- add consumers (the CAN, SDHC, I2C, DIU, FEC, USB, PSC peripherals)

11daf32be9 powerpc/512x: dts: disable MPC5125 usb module 
At the moment the USB controller's pin muxing is not setup
correctly and causes a kernel panic upon system startup, so
disable the USB1 device tree node in the MPC5125 tower board
dts file.

The USB controller is connected to an USB3320 ULPI transceiver
and the device tree should receive an update to reflect correct
dependencies and required initialization data before the USB1
node can get re-enabled.

bbca4d3917 powerpc/512x: dts: remove misplaced IRQ spec from 'soc' node (5125) 
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 ]
