7d0f8eec97 PCI: hv: Use pci_function_description[0] in struct definitions
The 2 structs can use a zero-length array here, because dynamic memory of
the correct size is allocated in hv_pci_devices_present() and we don't need
this extra element.

No functional change.

This code is not being built as a module by anyone:

  drivers/pci/host/Kconfig:  bool "NWL PCIe Core"

Remove uses of MODULE_DESCRIPTION(), MODULE_AUTHOR(), MODULE_LICENSE(),
etc., so that when reading the driver there is no doubt it is builtin-only.
The information is preserved in comments at the top of the file.

Explicitly disallow driver unbind, since that doesn't have a sensible use
case anyway, and it allows us to drop the ".remove" code for non-modular
drivers.  Delete several functions only used by the remove function.

Note that for non-modular code, builtin_platform_driver() uses the same
init level priority as module_platform_driver(), so this doesn't change
init ordering.

68a0bfec72 PCI: designware: Exchange viewport of MEMORYs' and CFGs/IOs'
When we have only two view ports in a DesignWare PCIe platform, iatu0
is used for both CFG and IO accesses.  When CFGs are sent to peripherals
(e.g., lspci), iatu0 frequently switches between CFG and IO.

For such scenarios, a MEMORY might be sent as an IOs by mistake.
Considering the following configurations:

  MEMORY  ->   BASE_ADDR: 0xb4100000, LIMIT: 0xb4100FFF, TYPE=mem
  CFG     ->   BASE_ADDR: 0xb4000000, LIMIT: 0xb4000FFF, TYPE=cfg
  IO      ->   BASE_ADDR: 0xFFFFFFFF, LIMIT: 0xFFFFFFFE, TYPE=io

Suppose PCIe has just completed a CFG access.  To switch back to IO, it
sets the BASE_ADDR to 0xFFFFFFFF, LIMIT 0xFFFFFFFE and TYPE to IO.  When
another CFG comes, the BASE_ADDR is set to 0xb4000000 to switch to CFG.  At
this moment, a MEMORY access shows up, since it matches with iatu0 (due to
0xb4000000 <= MEMORY BASE_ADDR <= MEMORY LIMIT <= 0xFFFFFFF), it is treated
as an IO access by mistake, then sent to perpheral.

This patch fixes the problem by exchanging the assignments of `MEMORYs' and
`CFGs/IOs', which assigning MEMORYs to iatu0, CFGs and IOs to iatu1.

We can still have issues with IO transfer, however memory transfer is used
predominantly therefore we are just minimizing the risk of failure.
Actually, we can not do much when we have only two viewports.  We can
either not allow the less frequent IO transfers at all, or can live with a
remote possibility of getting it corrupted.

This code is not being built as a module by anyone:

  drivers/pci/host/Kconfig:config PCI_XGENE
  drivers/pci/host/Kconfig:       bool "X-Gene PCIe controller"

Remove uses of MODULE_DESCRIPTION(), MODULE_AUTHOR(), MODULE_LICENSE(),
etc., so that when reading the driver there is no doubt it is builtin-only.
The information is preserved in comments at the top of the file.

Replace module_platform_driver() with builtin_platform_driver(), which uses
the same init level priority, so init ordering is unchanged.
