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.

BUG=chrome-os-partner:47688
BRANCH=none
TEST=emerge-glados coreboot (tested on chell board)
