mb/google/volteer: Add a DPTF policy for Eldrid
1. Enable dptf feature and remove fan control part from overridetree.cb 2. Update tcc offset to 5 3. Follow thermal validation and update PL2 max_power to 51 BUG=b:167931578, b:170357248 Signed-off-by: Nick Chen <nick_xr_chen@wistron.corp-partner.google.com> Change-Id: I99e429b90ed7de08385fe51ca742865b1266eef9 Reviewed-on: https://review.coreboot.org/c/coreboot/+/45860 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org>
