PS3, Line 11: 	# EC memory map range is 0x900-0x9ff and indexed access is through 0x380
can you please follow https://review.coreboot.org/c/coreboot/+/84919/3/src/mainboard/google/fatcat...

```
    # For platform selects EC_GOOGLE_CHROMEEC_MEMMAP_INDEXED_IO
    #	EC host command ranges are in 0x380-<range??>
    # For others 
    # 	EC host command ranges are in 0x900-0x9ff
```

btw, what is the range for 0x380 ? like how many bytes, depending on that you should modify the MSB of gen3_dec. if 8 bytes then MSB should be 4 like 0x00040381 (0x380-0x38f).
