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.

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.

To quote the author:
U-Boot provides a verified-boot feature based around FIT, but there is
no standard way of implementing it for a board. At present the various
required pieces must be built up separately, to produce a working
implementation. In particular, there is no built-in support for selecting
A/B boot or recovery mode.
This series introduces VPL, a verified program loader phase for U-Boot.
Its purpose is to run the verified-boot process and decide which SPL
binary should be run. It is critical that this decision happens before
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
verified boot. This series includes the phase itself, some useful Kconfig
options and a sandbox_vpl build for sandbox. No verfied-boot support is
provided in this series.
Most of the patches in this series are fixes and improvements to docs and
various Kconfig conditions for SPL.
Add an initial VPL build for sandbox. This includes the flow:
TPL (with of-platdata) -> VPL -> SPL -> U-Boot
To run it:
./tpl/u-boot-tpl -D
The -D is needed to get the default device tree, which includes the serial
console info.
Add a Makefile check for OF_HOSTFILE which is the option that enables
devicetree control on sandbox.

PCIe Mini CEM 2.1 spec added support for USB3.0 mode on MiniPCIe cards.
USB3.0 and PCIe share same pins and only one function can be active at the
same time. PCIe Mini CEM 2.1 spec says that determining function is
platform specific and spec does not define any dedicated pin which could
say if card is USB3.0-based or PCIe-based.
Implement this platform specific decision (USB3.0 vs PCIe) for WWAN
MiniPCIe slot on Turris Omnia via U-Boot env variable "omnia_wwan_slot",
similarly like is implemented forced mode for MiniPCIe/mSATA slot via
"omnia_msata_slot" env variable. Value "usb3" for "omnia_wwan_slot" would
mean to set USB3.0 mode and value "pcie" original PCIe mode.
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.
To set this MiniPCIe WWAN slot to USB3.0 mode, call U-Boot commands:
=> setenv omnia_wwan_slot usb3
=> saveenv
=> reset

Some PCIe-based MiniPCIe cards are broken and they do not ground PIN 43
which is required by PCIe mini CEM specs. Such broken cards are incorrectly
detected as mSATA cards because SATA specs requires that PIN 43 on mSATA
cards has to be disconnected.
PIN 43 on Turris Omnia is used only for MiniPCIe/mSATA card detection by
software in U-Boot SPL. Allow to override that U-Boot SPL detection by a
new "omnia_msata_slot" env variable (to value "pcie" or "sata") so broken
MiniPCIe cards can be used in combo mSATA/MiniPCIe slot too.
As configuration of PCIe vs SATA functionality is done in U-Boot SPL,
it is required to change env variable in permanent storage and reset the
board to take effect.
To force PCIe mode for broken MiniPCIe cards, call U-Boot commands:
=> setenv omnia_msata_slot pcie
=> saveenv
=> reset

BootROM maps SPI Flash to fixed address 0xD4000000 and this mapping is
active also when BootROM is executing binary kwbimage headers, which
includes also U-Boot SPL.
Therefore no initialization code is required to access SPI Flags from
U-Boot SPL. In proper U-Boot it is remapped to other location.
So in mvebu implementation of env_sf_get_env_addr() function returns
0xD4000000 when running in SPL and NULL when in proper U-Boot.
This change would allow to use U-Boot ENV in U-Boot SPL. Normally it is not
possible to read ENV because it is too big and U-Boot SPL does not have
such big malloc() pool to real all ENV variables.
