mainboard/google/hatch: Fix Puff _PR to toggle NIC ISOLATE# for S0ix
Turns out when going into S0ix we want the kernel to toggle de-assert to 0 for
the ISOLATE# pin on the NIC for S0ix not to be woken by PCIe traffic on PCH.
Upon resume the ISOLATE# pin on the NIC is then re-asserted for it to become
lively again.
BUG=b:147026979
BRANCH=none
TEST=Boot puff and do 1500 cycles of S0ix.
