If you have a look at the linux-firmware recipe (meta/recipes-kernel/linux-
firmware/linux-firmware_git.bb) you'll see that it splits out this firmware blob 
to a separate package called "linux-firmware-rtl8192cu", so add this to your 
IMAGE_INSTALL instead of "linux-firmware" (which will pull in all firmware) and 
you should be ready to go.

Cheers,
Paul
