burn_my_ec is an utility that flash an image embedded in its code.
We can not compile it as part of ec-[dev]utils, because we have
devices that firmware should be build as part of chrome-ec package.
Remove burn_my_ec, barely used.
Split the makefile to build just the host utility when requested.

Currently, LPC or I2C are compiled based on the board.h.
This is not really necessary, code can handle both at the same time.
Note that LPC and I2C access mode are backup modes, the main mode is
dev (accessing ECs through /dev/cros_XX).

This adds a new host commmand for sending RW updates to PD devices.
The host command has a variety of sub-commands for performing the
update, including: erase RW, reboot, write new hash, write flash.
To program zinger RW, you should send host commands in this order:
write new hash to all 0's
reboot (zinger boots into RO since RW hash doesn't match)
erase RW
write flash
write new hash to match contents of RW
reboot
This also adds an ectool command to write a new RW. Just pass it
the RW .flat or .bin file.

Instead of hardcoding the common files for host utils in the generic
rules, let's declare them in the build.mk file using the same system as
the Linux kernel build.
if a binary "foo" declared in "host-util-bin" or "build-util-bin" has a
matching "foo-objs" variable, it will be build from all objects declared
in "foo-objs" else it uses directly "foo.o" (single source file).
This is preparatory to add new "build" tools sharing common sources.
note: the dependencies on the utils are a bit less fine-grained as a
result of this change, but given the low number of tools, that should be
acceptable.

Add a way of easily setting up keyscan tests using a simple text file
format. The steps to run a test are as follows:
- read the test file
- read the key matrix information
- translate the ascii characters from tests into keyscan codes
- send the keyscan codes to the EC
- tell the EC to start the test
- wait for the required time, then collect what input we have received
- check that the input matches the expected input
