chrome ec: Fix ASL to use IO() instead of FixedIO()
FixedIO seems like a nice short version of IO but in reality it is limited to 10-bit ISA addresses and so should not really be used in most situations. Change all the references to use IO() directly instead. BUG=chromium:311294 BRANCH=none TEST=emerge-samus chromeos-coreboot-samus and check for iasl warnings using updated iasl compiler revision 20130117. Boot the imge and ensure that EC regions are still exported in /proc/ioports.
