soc/intel/skl: Add AML IccMax and remove unused info
This patch adds AML IccMax for VR configuration. From doc #594883, the IccMax for Core was changed to 28A, we need this patch to accommodate the changes. Besides, removes unused sku information from sku_icc_max_mapping structure. BUG=b:110890675 BRANCH=None TEST=Remove icc_max from DT & emerge-atlas coreboot chromeos-bootimage & Tested with AML-Y and KBL-Y SKUs.
