mb/google/cyan/spd/spd.c: Fix module part number transfer
With the increase of dimm->module_part_number size from 19 to 21 (commit
35b273eea3) "include/memory_info.h: Change part number field from 19 bytes
to 21", this code is now advancing outside DDR3 SPD designated space. The
correct size is already defined as LPDDR3_SPD_PART_LEN, use it. Also make
sure to 0 terminate the string.
BUG=b:77943312
TEST=Build cyan.
