mb/google/skyrim: Move common DPTC values to devicetree.cb
The Skyrim devices share a common set of DPTC values to enable booting
with low/no battery. Rather than duplicating them in each variant's
overridetree.cb, move them into the baseboard/devicetree.cb.
BUG=b:217911928
TEST=tast run <IP> power.ShutdownWithCommandBatteryCutoff
