util/spd_tools: Change Mendocino to use 0x13 for LP5x memory type

Browse Source 
Mendocino supports LP5x but currently doesn't support SPDs that use the
LP5x memory type, 0x15. This commit updates set 1 SPDs, which are
currently only used for mendocino, to use 0x13 for their memory type.

BUG=b:245509394
TEST=Generated SPDs, verified that only set 1 have changed to 0x13
