mb/google/poppy/variant/nautilus: Change SlowSlewRateForSa setting
If switch to VT2 on nautilus, screen flicker appears. We found if we
rollback the change of slew rate setting, then the flicker issue will
be gone: https://review.coreboot.org/c/coreboot/+/22588
But nautilus board needs slew rate tuning to reduce EE noise, so we
decided to change only SlowSlewRateForSa to 2 (Fast/8) instead of
rollback the whole change of the CL:22588. It can remove the flicker on
VT2.
