[v6,20/21] kernel.bbclass: remove support for type fitImage

From: Adrian Freihofer <adrian.freihofer@siemens.com>

kernel.bbclass is no longer involved in FIT image creation. Whether a
FIT image is built now depends entirely on whether the linux-yocto-fitimage
recipe (or any other recipe capable of producing a FIT image) is selected
for the build.
As a result, specifying the kernel image type "fitImage" in
KERNEL_IMAGETYPE or KERNEL_IMAGETYPES is no longer necessary and gets
removed.

Can this be a little be more specific ? Indicating the migration
path (the new recipe) would help someone seeing the message.

Minor 'nit, but the above change is unrelated to the fit image rework :)
