mb/google/fatcat: Adjust EC host command range for fatcat_ish variant
Adjusts the EC host command range for the fatcat_ish variant
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.
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
BUG=b:370984186
TEST=Able to build fatcat/fatcat_ish w/o any error.
