chromeos-ec: Support unified builds

Support building the EC for multiple models in a single board. This uses
the unified build approach. The list of models to build is defined by the
EC_FIRMWARE_UNIBUILD and EC_FIRMWARE_EXTRA_UNIBUILD variables.

BUG= chromium:680151 
BRANCH=none
TEST=USE="quiet unibuild" emerge-reef chromeos-ec
Look in build/reef/firmware/ and see that firmware exists for reef, pyro,
snappy. So far it is untested (until I get some more hardware).

chromeos-ec: Display the target we are building for

This just helps to see what is happening for long multi-target builds.

chromeos-ec: Don't install the 'main EC' with unified builds

There is no 'main EC' with unified builds. We just have the various
targets needed by each model. Update the install method to deal with this.
This avoids installing superfluous files in /build/firmware.

BUG= chromium:680151 
TEST=emerge-reef chromeos-ec
See there are no EC files in /build/reef/firmware

coreboot: Pick up the correct EC for the current model

At present we collect the EC from the /firmware directory. But with
unified builds we must look in the model directory instead. Fix this.

BUG= chromium:680151 
TEST=emerge-reef coreboot
See that it succeeds and places the Pyro EC binary in the Pyro image, not
the Reef EC.

OK this seems to work correctly now.
