ene_lpc: remove ENE LPC programmer

Best efforts were made to upstream older Chromebook support for good
intentions for folks interested. However, we no longer have the hardware
available to test and maintain the code as the hardware is now end of
life. Therefore the code state has sadly fallen into a unknown state.

BUG=none
BRANCH=none
TEST=builds and ninja test passes
