mb/google/fatcat: Adjust EC host command range for microchip EC
This commit adjusts the EC host command range for the Fatcat board to 0x800-0x807 & 0x200-0x20f. This change is necessary because the microchip EC used on the Fatcat board has a smaller host command range than the ITE/Nuvoton ECs used on other Fatcat variants. The `gen1_dec` register in the devicetree is updated to reflect this change. As per boot log, the `gen1_dec` aka offset 0x84, base address is 800 and size is 8 bytes.
