Ard Biesheuvel Dec. 6, 2016, 1:05 p.m.
Create a new Styx platform driver StyxSataPlatformDxe which contains the
existing platform specific SATA initialization code (including the AHCI
register descriptions in SataRegisters.h), but uses the new non-discoverable
device protocol to register the platform AHCI devices.

This has two advantages:
- we can use generic drivers for the non-discoverable PCI I/O emulation, and
  for the AHCI support built on top of it,
- we can register both SATA devices, allowing us to use all 14 ports on
  Overdrive B1
