chromeec: Support accessing memmap data over port 62/66

Hardware / Coreboot - Shawn Nematbakhsh [chromium.org] - 22 April 2015 01:49 UTC

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
