mb/google/guybrush/var/nipperkin: update telemetry settings
Currently, the AMD SDLE stardust test fails with incorrect VDD/SOC
scale/offset value, it needs to 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: 92165 -> 73457
VDD offset: 412 -> 291
SOC scale: 30233 -> 30761
SOC offset: 457 -> 834
BUG=b:200194315
BRANCH=guybrush
TEST=emerge-guybrush coreboot chromeos-bootimage
pass AMD SDLE/Stardust test
