chromeec: Support accessing memmap data over port 62/66
Some platforms cannot access the 900h-9ffh region over the LPC bus, so
it's necessary to access memmap data over the ACPI cmd / data ports.
BUG=chrome-os-partner:38224
TEST=Manual on Samus. Define EC_GOOGLE_CHROMEEC_ACPI_MEMMAP. Verify
system boots cleanly and battery status is updated immediately on plug /
unplug.
BRANCH=None
