fs/ext2: Remove support for auto-calculation of rootfs size

Browse Source 
Auto-calculation of the rootfs size cannot be done in a reliable way
as it depends on the host filesystem and is broken on non ext4 host
(see bugs [1] [2]). So let the user specify the size he wants for his
rootfs.

[Thomas: as suggested by Arnout, use 60 MB as the default size instead
of 64 MB.]

help
Since the support for auto calculation of the filesystem size has been
removed, this option is now useless and must be 0.
You may want to check that BR2_TARGET_ROOTFS_EXT2_BLOCKS matchs
your needs.
