[PATCH 0/8][Version 2] MPC5121 Updates

[John Rigby]

The following patches contain updates for MPC5121

1/8
    No change since last submission.
    Updates the device tree.
2/8
    Adds a clock driver. Cleanup based on input from Stephen Rothwell.
3/8
    No change since last submission.
    Adds support for generic boards.  This is nearly identical to
    David Jander's patch but does not delete the ADS board option.
    ADS is not a candidate for generic since it has an on board
    cpld that does pci interrupt routing.
4/8 
    No change since last submission.
    Adds support for the CPLD on the MPC5121ADS board.
5/8 
    Cleans up pci config in arch/powerpc/Kconfig to make it
    less messy to add an new platform that has pci.
6/8 
    Moves mpc83xx_add_bridge from a/p/p/83xx/pci.c to
    a/p/p/sysdev/fsl_pci.c. So it can be used by other platforms
    using the same pci core.
7/8 
    Adds pci support for mpc5121 and uses mpc83xx_add_bridge.
8/8 
    No change since last submission (except now 8/8 instead of 6/6).
    Hides the pci bridge
