    exynos/snow: Move core/memory clock-related and board ID code
    
    This patch moves ARM core and DRAM timing functions around to simplify
    the dependencies for system_clock_init().
    
    The original code was architected such that the system_clock_init()
    function called other functions to obtain core and memory timings.
    Due to the way memory timing information must be obtained on Snow,
    which entails decoding platform-specific board straps, the bottom-
    up approach resulted in having the low-level clock init code
    implicitly depend on board and vendor-specific info:
    
    main()
      ->system_clock_init()
        -> get_arm_ratios()
           -> CPU-specific code
        -> clock_get_mem_timings()
           -> board_get_revision()
              -> read GPIOs (3-state logic)
              -> Decode GPIOs in a vendor-specific manner
           -> Choose memory timings from module-specific look-up table
      ...then proceed to init clocks
    ...come back to main()
    
    The new approach gathers all board and vendor-specific info in a
    more appropriate location and passes it into system_clock_init():
    main()
      -> get_arm_ratios()
         -> CPU-specific code
      -> get_mem_timings()
         -> board_get_config()
            -> read GPIOs (3-state logic)
            -> Decode GPIOs in a vendor-specific manner
         -> Choose memory timings from module-specific look-up table
      -> system_clock_init()
    ...back to main()
