google/kukui: Include LCD module identifier (LCM ID) into SKU ID
Kukui is using MIPI display panel and needs some identifier to tell payloads which LCD module is installed, and to select right kernel device tree. Following Scarlet, the decision is to embed LCD module ID as part of SKU ID. The LCM ID is using a different voltage mapping table from the rest. Considering the complexity in computation of SKU ID, it is better to move the cache logic from get_index to caller. Also revise the mapping table since ADC on 8183 only supports 12 levels. BUG=b:129299873 TEST=make -j; boots on Kukui Rev2 unit.
