2019-07-11google/kukui: Adjust LCM ID voltagesYu-Ping Wu
Currently some of the LCM ID voltage gaps are below 100mV. For example, the voltage difference between ID 2 and 3 is 503-440=63mV. To reduce the risk of misrecognition from the hardware level, the voltages are adjusted so that all the voltage gaps are larger than 100mV. The RD2 resistor values are also updated.

2019-07-11board/kukui: Remove ADC tolerance from boardidHung-Te Lin
The tolerance of ADC is +-10mV, but the resistors may also introduce 1% variation, and causing the final measured voltage to vary around 5%. By the advisory from hardware team, checking the tolerance seems not really solving or helping anything so we should just ignore that and try to find best matched ID (this also aligns to what Gru did).

2019-04-22board/kukui: Support ADC value for NCHung-Te Lin
When the components like LCM ID are not installed (i.e., NC), ADC will return some value with much larger variation from standard value (out of the tolerance we set). To support that, we should check tolerance only on non-NC voltages. Also improve the error messages so we can see the ADC raw values instead of simple assertion error (which makes debugging more difficult since we have to build another firmware image just to print the values). BUG=None TEST=Booted on Kukui and got correct SKU ID for NC LCMID.

2019-04-15google/kukui: Include LCD module identifier (LCM ID) into SKU IDHung-Te Lin
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.
