    intel/sandybridge/raminit: fix ODT setting
    
    Count DIMMs on current memory channel instead of all memory channels.
    
    The current code is only able to correctly handle the following memory
    configurations:
    
    One DIMM installed in either channel.
    Four DIMMs installed, two in each channel.
    Two DIMMs installed, both in the same channel.
    
    For systems that have any other configuration the DRAM On-Die-Termination
    setting is wrong.
    For example:
    
    Two DIMMs installed, one in each channel.
    
    Test system:
    * Gigabyte GA-B75M-D3H (Intel Pentium CPU G2130)
