ec_commands: Rename 'renew' to 'live' in EC_CMD_USB_PD_CHIP_INFO

Semantics of renew field in EC_CMD_USB_PD_CHIP_INFO is changing as
follows:
0 -> Return hard-coded info for Vendor ID/Product ID and cached info for
the Firmware Version
1 -> Return the live chip info for Vendor ID/Product ID/Firmware Version
Also rename the 'renew' field to 'live' to match the new semantics.

BUG=b:128820536,b:119046668
BRANCH=None
TEST=make -j buildall; Boot to ChromeOS.
