Hao Wu 82bf462e3a MdeModulePkg/NonDiscoverablePciDev: Fix type mismatch in switch/case
Fix switch/case statement type mismatch in functions PciIoMemRead &
PciIoMemWrite.

Parameter 'Width' is of enum type EFI_PCI_IO_PROTOCOL_WIDTH, but the enum
type provided in 'switch (Width)' block is of type
EFI_PCI_ROOT_BRIDGE_IO_PROTOCOL_WIDTH.

Ard Biesheuvel 8b78de74dc MdeModulePkg/NonDiscoverablePciDevice: add missing cast and EFIAPI modifiers
Add missing EFIAPI modifiers to the functions that are exposed via the
PCI I/O protocol.

At the same time, add a missing UINT8 cast which breaks the build on
Visual Studio.

Ard Biesheuvel a42e6d448d MdeModulePkg: implement generic PCI I/O driver for non-discoverable devices
This implements support for non-discoverable PCI compatible devices, i.e,
devices that are not on a PCI bus but that can be controlled by generic PCI
drivers in EDK2.

This is implemented as a UEFI driver, which means we take full advantage
of the UEFI driver model, and only instantiate those devices that are
necessary for booting.

Care is taken to deal with DMA addressing limitations: DMA mappings and
allocations are moved below 4 GB if the PCI driver has not informed us
that the device being driven is 64-bit DMA capable. DMA is implemented as
coherent, support for non-coherent DMA is implemented by a subsequent patch.
