    Subject[PATCH v8 21/42] ARM: davinci: da830: add new clock init using common clock framework
    Date
    This adds the new board-specific clock init in mach-davinci/da830.c
    using the new common clock framework drivers.

    The #ifdefs are needed to prevent compile errors until the entire
    ARCH_DAVINCI is converted.

    Also clean up the #includes since we are adding some here.

    v8 changes:
    - none

    v7 changes:
    - add clock platform device declarations
    - register platform devices instead of registering clocks directly
    - clkdev lookup is moved to drivers/clk
    - add davinci prefix to commit description

    v6 changes:
    - add blank lines between function calls
    - include da8xx_register_cfgchip()
