soc/intel/alderlake: add power limits for Alder Lake-M 282 SKU
There are two different types of 282 SKU available with TDP
of 15W and 12W for Alder Lake-M SoC. This patch adds support
for these TDP values for 282 SKU as per document 643782.
BUG=None
BRANCH=None
TEST=Build FW and test on adlrvp board
