bzip2/lzma: don't ask for compression mode for the default initramfs
Impact: Kconfig noise reduction, documentation The default initramfs is so small that it makes no sense to worry about the additional memory taken by not double-compressing it. Therefore, don't bug the user with it. Also, improve the description of the option, which was downright incorrect. Signed-off-by: H. Peter Anvin <email@example.com>
