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.
AP FW Boot log:
[SPEW] PCI: 00:00:1f.0 resource base 800 size 8 align 0 gran 0 limit 0 flags c0000100 index 84
BUG=b:376207365
TEST=Able to build and boot google/fatcat w/o any error.
without this patch:
[SPEW ] LPC: Trying to open IO window from 800 size 8
[ERROR] LPC: Cannot open IO window: 800 size 8
[ERROR] No more IO windows
with this patch:
[SPEW ] LPC: Trying to open IO window from 800 size 8
