Subject: [PATCH] mb/google/octopus: Add custom SAR values for Blooguard

Google project name is Bloog.
Bloog is 12-inch LCD.
Blooguard is 14-inch LCD so would prefer to use a different SAR values instead.
Use sku-id to load the SAR values.

BUG=b:135078377
BRANCH=octopus
TEST=build and verify SAR load by sku-id
