[libata sata_sil24] add support for 3131/3531
This patch adds support for sil_3131 and sil_3531. Both are identical to 3124 except that they have only one port. Bits 30 and 31 of ata_port_info->host_flags is used to encode available port numbers. Version number is bumped to 0.22. Edward Falk supplied all the necessary information and preliminary patch.
