mb/google/fizz: Set Pmax to 120 for all SKUs
The Pmax is calcuated from MAX(Psku1, Psku2), where Psku1, Psku2 are
estimated Pmax power of U42 and U22 skus. For U42 sku, the Pmax is PL4
(71W) + ROPmax (49W) = 120W; for U22 SKU, the Pmax is PL4 (43W) +
ROPmax (49W) = 92W. So Pmax is set to MAX(120W, 92W) = 120W.
BUG=b:71594855
BRANCH=None
TEST=Make sure correct pmax value is being passed into fsp
