libata-sff: fix 32-bit PIO ATAPI regression
Commit 871af1210f13966ab911ed2166e4ab2ce775b99d (libata: Add 32bit PIO support) has caused all kinds of errors on the ATAPI devices, so it has been empirically proven that one shouldn't try to read/write an extra data word when a device is not expecting it already. "Don't do it then"; however, still use a chance to do 32-bit read/write one last time when there are exactly 3 trailing bytes. Oh, and stop pointlessly swapping the bytes to and fro on big-endian machines by using io*_rep() accessors which shouldn't byte-swap. This patch should fix the kernel.org bug #12609.
