mb/google/poopy/variants/nami: Add Pmax setting

This patch adds the Pmax setting in device tree. The Pmax is from
MAX(PL4_sku1, PL4_sku2, ..) + ROPmax. Given ROPmax is 30W and
the maximum PL4 is from U42, hence the Pmax = 71W + 30W = 101W.

BUG=b:72138778
BRANCH=None
TEST=USE=fw_debug emerge-nami chromeos-mrc coreboot chromeos-bootimage
         & ensure the Pmax value is passed to FSP-S.
