fs/ext2: deprecate BR2_TARGET_ROOTFS_EXT2_EXTRA_INODES option

Browse Source 
Soon, the ext{2,3,4} rootfs image will no longer be generated with
genext2fs, but using mke2fs instead which has no support for the extra
inode number option.

So, deprecate the BR2_TARGET_ROOTFS_EXT2_EXTRA_INODES option and
recommend, in lieu, to set the total inode number, taking account of
the extra ones if needed.

Buildroot now uses mkfs.ext2/3/4 to generate ext2/3/4
images. It now automatically selects the number of inodes
based on the image size. The extra number of inodes can no
longer be provided; instead, provide the total number of
inodes needed in BR2_TARGET_ROOTFS_EXT2_INODES.
