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.
