Tested on MPC5125 Tower evaluation board with
mpc512x_defconfig compile configuration.

In detail, supports for:
- PSC / UART
- RTC
- ETH
- DIU
- I2C

Provide common mpc5121.dtsi file for mpc5121 SoC and modify
mpc5121ads.dts to use mpc5121.dtsi.

The DIU driver should bind against "fsl,mpc5121-diu"
directly. Add this compatible property to the match
table and fix DTS and platform code accordingly.

Collects several changes needed after applying
previous mpc5121 platform and driver patches:

- Add mpc5121 reset module node
- Clean up and fix NAND description, remove unused properties
  here and correct NAND flash chip size.
- Clean up I2C nodes: remove obsolete "cell-index" properties,
  add "fsl,preserve-clocking" property
- Add I2C RTC node for m41t61 RTC
- Add I2C nodes for AD7414 temperature sensor and AT24C32CD3 EEPROM
- Fix compatible property in DMA node
- Clean up CAN nodes, remove unused "cell-index" properties
- Fix compatible property in DIU node
- USB node changes:
    - use "fsl,mpc5121-usb2-dr" compatible property only
    - remove "port0" and "port1" properties as these are only used
      for multi-port host(MHP) module which is not available
      on MPC5121.
    - use 'fsl,invert-drvvbus' and 'fsl,invert-pwr-fault' in
      USB node for internal PHY to specify polarities
      of the appropriate port pins.

The 'fsl5200-clocking'-property was dropped since

Current device tree is only bare bones.  This patch adds nodes to make
it a complete tree for the MPC5121ads.

Added nodes include:
    mbx      - opengl coprocessor
    nfc      - nand flash controller
    cpld-pic - on board cpld
    rtc
    clock    - clock control
    pmc      - power management control
    gpio
    mscan    - can module
    i2c
    axe      - audio coprocessor
    display  - display interface unit
    mdio
    ethernet
    usb
    ioctl    - pin config
    pata
    ac97     - PSC configured as AC97
    pscfifo  - psc fifo configuration
    dma
    pci

Fix typo in header changing MDS to ADS.

Add a compatible property of the form "fsl,mpc5121-..."
to nodes missing one.

Changed localbus compatible to fsl,mpc5121-localbus, this does
not break anything because the only code that uses it finds it
via the node name, not compatible.
