src/northbridge/amd/amdmct: Add option to override bad SPD checksum

Certain DIMMs, for example DIMMs on which the EEPROM has been modified
    by the end user, may not contain a valid SPD checksum.  While this is
    not a normal condition, it may be useful to allow a checksum override
    while memory timing parameters are being altered, e.g. in the course
    of overclocking or underclocking, or when recovering from a bad SPD
    write.

This is an advanced level feature primarily useful for debugging
    and development.
