soc/amd/common/block/pi/amd_late_init.c: Fix illegal memory access
Found-by: Coverity (CID 1387031: Memory - illegal accesses
(BUFFER_SIZE_WARNING)). Calling strncpy with a maximum size argument of
19 bytes on destination array "dimm->module_part_number" of size 19 bytes
might leave the destination string unterminated. Fix the size parameter.
BUG=b:76202696
TEST=Build and boot kahlee, using special debug code to see the output
strings, which was later removed.
