mb/google/kukui: fix the issue of getting error panel_id
Current get panel_id is over sku_id() >> 4, but sku_id is combined with
wfc_id/lcm_id/sku_id, so the panel_id value is wfc_id << 4 | lcm_id()
in fact. When wfc_id is not 0, the panel_id will be wrong. So only get
the low 4 bits for the panel_id.
