libata: add human-readable error value decoding
This adds human-readable decoding of the ATA status and error registers
(similar to what drivers/ide does) as well as the SATA Serror register
to libata error handling output. This prevents the need to pore
through standards documents to figure out the meaning of the bits
in these registers when looking at error reports. Some bits that
drivers/ide decoded are not decoded here, since the bits are either
command-dependent or obsolete, and properly parsing them would add
too much complexity.
