google/glados: Set FSP params for min assertion widths and serirq
- Enable serial irq configuration in FSP. - Set minimum assertion width values for FSP to configure. - Set I2C4 voltage to 1.8V. - Enable SaGv feature to dynamically train memory frequency. - Disable Deep S3 to match chell so DeepSx story is consistent on skylake-y boards.
