mb/google/guybrush/var/nipperkin: update telemetry settings
Update the two load line slope settings for the telemetry. AGESA sends these values to the SMU, which accepts them as units of current. Proper calibration is determined by the AMD SDLE tool and the Stardust test. VDD scale: 73331 -> 94623 VDD offset: 1893 -> 1847 SOC scale: 31955 -> 29904 SOC offset: 852 -> 756 BUG=b:217963719 BRANCH=guybrush TEST=emerge-guybrush coreboot chromeos-bootimage pass AMD SDLE/Stardust test Change-Id: Icad97644dd9391a325dfe1dbb1ec176e1f6d3dc3 Signed-off-by: Kevin Chiu <kevin.chiu.17802@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/62980 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Felix Held <felix-coreboot@felixheld.de> Reviewed-by: Karthik Ramasubramanian <kramasub@google.com> Reviewed-by: Raul Rangel <rrangel@chromium.org>
