[PATCH] libata: implement ata_dev_id_c_string()
ata_dev_id_c_string() reads ATA string from the specified offset of
the given IDENTIFY PAGE and puts it in the specified buffer in trimmed
and NULL-terminated form. The caller must supply a buffer which is
one byte larger than the maximum size of the target ID string.
