Set of legacy mode SATA enchancements:
- Implement proper combined mode decoding for Intel controllers to properly identify SATA and PATA channels and associate ATA channels with SATA ports. This fixes wrong reporting and in some cases hard resets to wrong SATA ports. - Improve SATA registers support to handle hot-plug events and potentially interface errors. For ICH5/6300ESB chipsets these registers accessible via PCI config space. For later ones they may be accessible via PCI BAR(5). - For controllers not generating interrupts on hot-plug events, implement periodic status polling. Use it to detect hot-plug on Intel and VIA controllers. Same probably could also be used for Serverworks and SIS.
