kernel: remove old "rootfs" splitter
A year ago I made this old splitter obsolete (see r42828), it's time to
completely remove it now. For all this time we got these warnings:
"Dedicated partitioner didn't create "rootfs_data" partition, please fill a bug report!"
and
"Support for built-in "rootfs_data" splitter will be removed, please use CONFIG_MTD_SPLIT_SQUASHFS_ROOT"
but I'm not aware of any bug reports related to that.
