Add EC_CMD_GET_FLASH_INFO version 1
This adds two new fields: the ideal write size for best EC flashing
performance (e.g., page mode instead of word mode), and a flags field
with a flag to indicate whether the EC erases its bits to 0 or 1.
The EC still supports the old version 0 command, since u-boot and
flashrom expect that to work.
BUG=chrome-os-partner:20973
BRANCH=(all haswell); this will speed up flashing and software sync
TEST=ectool flashinfo
1. old EC, new ectool -> only reports version 0 info
2. new EC, old ectool -> only reports version 0 info
3. new EC, new ectool -> reports new fields
