The firmware-imx generates several sub-packages that are added in
MACHINE_FIRMWARE[1] variable which is added in
MACHINE_EXTRA_RRECOMMENDS. So adding the firmware-imx is doing nothing
as it is an empty package.

1. http://git.yoctoproject.org/cgit/cgit.cgi/meta-fsl-arm/tree/conf/machine/include/imx-base.inc#n56

MACHINE_EXTRA_RRECOMMENDS is included in the packagegroup-machine-base
which IS NOT included in the core-image-minimal image. The smallest
image which includes it core-image-base.

I hope this clarifies the reason it didn't work for you. :)
