inteltool/ahci: Add Skylake support

Browse Source 
The SATA device moved from 0:1f.2 to 0:17.0, 0:1f.2 became PMC. We
detect that by checking the PCI device class.

The ABAR MMIO space has grown to 2KiB and up to 8 ports are supported
now. For backwards compatibility, only dump port registers of ports
that are enabled in the Ports Implemented (PI) register.
