mb/google/guybrush/var/nipperkin: update telemetry settings
Update the two load line slope settings for the SVID3 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: 73457 -> 73331 vdd offset: 291 -> 1893 soc scale: 30761 -> 31955 soc offset: 834 -> 852 BUG=b:207299255 BRANCH=guybrush TEST=1. emerge-guybrush coreboot 2. pass AMD SDLE/Stardust test Change-Id: I9c9dd4883fd21a70a1e7a50f25a4f76df1e56bc6 Signed-off-by: Kevin Chiu <kevin.chiu.17802@gmail.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/60243 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Paul Menzel <paulepanter@mailbox.org> Reviewed-by: Rob Barnes <robbarnes@google.com>
