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
