zephyr: Enable link time optimization (LTO)
The upstream Zephyr repo does not support LTO. Reconfigure the
platform/ec source files into a cmake library so the LTO option can be
enabled for all the platorm/ec sources.
This reduces the Volteer flash image size by 9176 bytes.
BUG=none

TEST=zmake testall
