Add annotations to allow the compiler to check printf-style format
strings in the EC.

This code is a port of the sample loader application included in the
FPGA update. Only the pieces relevant to straight verification and
boot were ported.
The loader generates a hash, inputs to which are the image body, state
of fuses and state of flash INFO region, and the output is the value,
which will unlock the region for execution, if it is correct.
Only one image load is attempted, the image is supposed to be located
in the flash at the offset of CONFIG_RW_MEM_OFF.
BRANCH=none
BUG=chrome-os-partner:43025
TEST=with the rest of the patches applied the RO image successfully
verifies and starts up the RW image.

The CR50 board will have to have a very different RO image, let's make
it possible to override the default list of objects compiled by the
top level makefile with a board/chip specific list compiled in the
appropriate build.mk file.
The CR50 RO will never run on its own for long time, it will always
load an RW and go straight to it, so there is no need in running under
the OS control, using sophisticated console channel controls, etc.
The gist of the functionality is verifying the RW image to run and
setting up the hardware to allow the picked image to execute, it will
be added in the following patches. This change just provides the
plumbing and shows the 'hello world' implementation for the customized
RO image.
A better solution could be the ability to create distinct sets of make
variables for RO and RW, a tracker item was created to look into this.

BUG=chrome-os-partner:43025, chromium:551151
TEST=built and started ec.RO.hex on cr50, observed the 'hello world'
message on the console.
