To quote the author:
The virtio PCI drivers forgo a number of consistency checks,
particularly around pointer validation and bounds checking. This series
focuses on the modern driver to add those checks.
The start of the series adds and fixes some basic bounds checks. Later
patches ensure PCI addresses fall within the expected regions rather
than any arbitrary address. This is acheived by introducing range
parameters to a few of the dm_pci_* functions that allow the ranges to
be checked.
The series also adds a few new configs to allow parts of virtio and PCI
to be disabled where the features may be unused and the current
implementations don't have the needed consistencty checks.
The virtio PCI capabilities describe regions of memory that should be
mapped. Map those with dm_pci_map_bar() which will ensure they are valid
PCI regions.

Prepare for calls to `virtio_pci_map_capability()` failing by returning
NULL on error. If this happens, later accesses to the pointers would be
unsafe so cause the probe to fail if such an error occurs.

Add mask parameter and reorder length parameter to match the other PCI

When converting addresses, apply a mask to the region flags during
lookup. This allows the caller to specify which flags are important and
which are not, for example to exclude system memory regions.
The behaviour of the function is changed such that they don't
preferentially search for a non-system memory region. However, system
memory regions are added after other regions in decode_regions() leading
to a similar outcome.

Evolve dm_pci_map_bar() to include an offset and length parameter. These
allow a portion of the memory to be mapped and range checks to be
applied.
Passing both the offset and length as zero results in the previous
behaviour and this is used to migrate the previous callers.

When converting between PCI bus and physical addresses, include a length
parameter that can be used to check that the entire range fits within
one of the PCI regions. This prevents an address being returned that
might be only partially valid for the range it is going to be used for.
Where the range check is not wanted, passing a length of 0 will have the
same behaviour as before this change.

Read the virtio PCI capability out of the device configuration space to
a struct rather than accessing fields directly from the configuration
space as they are needed. This both makes access to the fields easier
and avoids re-reading fields.
Re-reading fields could result in time-of-check to time-of-use problems,
should the value in the configuration space change. The range check of
the `bar` field and the later call to `dm_pci_read_bar32()` is an
example of where this could happen.

If CMD_BOOTMENU_ENTER_UBOOT_CONSOLE is disabled, "Quit" entry
