mb/google/skyrim/: Set system_configuration to 3 to avoid SMU call

Update system_configuration to 3 for 15W. Specification "FT6
Infrastructure Roadmap #57316" incorrectly lists system config index
of 4 for 15W. Setting to 4 will cause an additional call to the SMU
that is not needed and will add boot delay. Both SMU and FSP interpret
configs > 3 as 3.

BUG=b:267294958
TEST=Confirm extra message "Service Request 0x5F" not in log.
