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.

Its purpose is to run the verified-boot process and decide which SPL

SPL runs, since SPL sets up SDRAM and we need to be able to update the
SDRAM-init code in the field.
Adding VPL into the boot flow provides a standard place to implement

A385 SoC on Turris Omnia has configurable fifth SerDes line (exported to
MiniPCIe WWAN slot with SIM card) either to USB3.0 or PCIe functionality,
so implementation of this new PCIe Mini CEM 2.1 feature is simple, by just
configuring SerDes to USB 3.0 mode.
Other twos MiniPCIe slots on Turris Omnia do not have this new
functionality as their SerDes lines cannot be switched to USB3.0
functionality.
Note that A385 SoC does not have too many USB3.0 blocks, so activating
USB3.0 in MiniPCIe cause that one external USB3.0 USB-A port would loose
USB3.0 functionality and would be downgraded just to USB2.0.
By default this MiniPCIe WWAN slot is in PCIe mode, like before.

led: gpio: Use NOP uclass driver for top-level node
The top level DT node of gpio-leds is not a LED itself, bind NOP uclass
driver to it, and bind different LED uclass driver to its subnodes which
represent the actual LEDs. This simplifies the probe() implementation
and fixes the bogus top-level not-an-LED in 'led list' command output:
```
=> led list
led Error -121 <--- This is removed/fixed by this patch

led: gpio: Check device compatible string to determine the top level node
Since 87d0e5d4c05 ("led: gpio: Drop duplicate OF "label" property parsing"),
all LED nodes have some sort of label. Use device_is_compatible(..."leds-gpio")
to determine whether this is a top-level node, since it is only the top
level node which is compatible with "leds-gpio", the GPIO LEDs subnodes
are not.

led: Mark device instance with DM_FLAG_PROBE_AFTER_BIND
Calling device_probe() from uclass .post_bind() callback has all kinds
of odd side-effects, e.g. device instances not being available just yet.
Make use of the DM_FLAG_PROBE_AFTER_BIND instead, mark device instances
which need to be probe()d in order to configure the LED default state
with this flag and let the DM core do the device_probe() at the right
time instead.

dm: core: Add DM_FLAG_PROBE_AFTER_BIND flag
Introduce DM_FLAG_PROBE_AFTER_BIND flag, which can be set by driver or
uclass in .bind(), to indicate such driver instance should be probe()d
once binding of all devices is complete.
This is useful in case the driver determines that hardware initialization
is mandatory on boot, and such initialization happens only in probe().
This also solves the inability to call device_probe() from .bind().
