Version 1 of EC_CMD_FLASH_WRITE will use as big a write as possible given
the available command parameter space. Falls back to 64 byte writes on old
platforms.
BUG=chrome-os-partner:20571
BRANCH=none
TEST=Copy burn_my_ec onto a link and run it. Write size should be 64 bytes
for the first half of the update (since the old EC doesn't support ver.1
of the write command) and 240 bytes for the second half of the update.
