mec1322: Changed to generate ec.bin for the firmware binary.
Previously for the mec1322 chip an ec.bin file was created in the normal way
and then it was "packed" in a post-processing stage to produce ec.spi.bin.
This change allows a chip or board build.mk file to specify the rules used to
produce ec.bin, and uses this for the mec1322 to do the packing. This means
that we can use the standard "ec.bin" name, and do not need to alter other
scripts, such as the script which creates chromeos-firmwareupdate.
BUG=None
TEST=buildall -j, flash on strago and see it still works.
BRANCH=NONE
