Treat dimm addr_map 0 non-existent. addr_map default is 0, we don't set
it if Hw is not present. Also change the test case default to avoid 0.
SODIMM SMbus address 0x50 to 0x53 is commonly used.

This patch adds some spd_cache functions. They are for implementing the
spd_cache. It's for reducing the SPD fetch time when device uses SODIMMs.
The MRC cache also includes SPD data, but there is no public header file
available to decode the struct of MRC. So SPD cache is another solution.
