ec: Reserve correct ioport regions for Chrome OS EC to use
The LPC-based ChromeOS EC uses several ioport regions to communicate with
the AP. In order for the new unified userspace access method to work, we
need them to be reserved by the BIOS.
Before /proc/ioports shows:
0800-0803
0804-08ff
We'd like just a single 256-byte region at 0x800, but ASL can't handle that.
So this will work:
0800-087f
0880-08ff
BUG=chromium:249009
BRANCH=none
TEST=manual
cat /proc/ioports, look for the correct regions.
