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
