libata: make SFF support optional
Now that SFF support is completely separated out from the core layer, it can be made optional. Add CONFIG_ATA_SFF and let SFF drivers depend on it. If CONFIG_ATA_SFF isn't set, all codes in libata-sff.c and data structures for SFF support are disabled. This saves good number of bytes for small systems. Signed-off-by: Tejun Heo <htejun@gmail.com>
