PCI: designware: Make MSI ISR shared IRQ aware

On i.MX6 the host controller MSI IRQ is shared with PCI legacy INTD.  Make
sure we don't bail too early from the IRQ handler.

The issue is fairly theoretical as it would require a system setup with a
PCIe switch where one connected device is using legacy INTD and another one
using MSI, but better fix it now.

PCI: generic: Add generic PCI host controller driver

Add support for a generic PCI host controller, such as a
firmware-initialised device with static windows or an emulation by
something such as kvmtool.

The controller itself has no configuration registers and has its address
spaces described entirely by the device-tree (using the bindings from
ePAPR).  Both CAM and ECAM are supported for Config Space accesses.

Add corresponding documentation for the DT binding.

vfio/pci: Fix unchecked return value

There's nothing we can do different if pci_load_and_free_saved_state()
fails, other than maybe print some log message, but the actual re-load
of the state is an unnecessary step here since we've only just saved
it.  We can cleanup a coverity warning and eliminate the unnecessary
step by freeing the state ourselves.

vfio/iommu_type1: Avoid overflow

Coverity reports use of a tained scalar used as a loop boundary.
For the most part, any values passed from userspace for a DMA mapping
size, IOVA, or virtual address are valid, with some alignment
constraints.  The size is ultimately bound by how many pages the user
is able to lock, IOVA is tested by the IOMMU driver when doing a map,
and the virtual address needs to pass get_user_pages.  The only
problem I can find is that we do expect the __u64 user values to fit
within our variables, which might not happen on 32bit platforms.  Add
a test for this and return error on overflow.  Also propagate use of
the type-correct local variables throughout the function.

The above also points to the 'end' variable, which can be zero if
we're operating at the very top of the address space.  We try to
account for this, but our loop botches it.  Rework the loop to use
the remaining size as our loop condition rather than the IOVA vs end.
