Configure an IO region and window for PNP identical to how MEM region is
set up. Linux does this only if the DT defines a pcie-io-aperture
property for the SOC, but since all supported boards do this should not
be needed.

This name is far too long. Rename it to remove the 'data' bits. This makes
it consistent with the platdata->plat rename.

We use 'priv' for private data but often use 'platdata' for platform data.
We can't really use 'pdata' since that is ambiguous (it could mean private
or platform data).
Rename some of the latter variables to end with 'plat' for consistency.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

At present this method uses a non-const udevice pointer, but the call
should not modify the device. Use a const pointer.

The non-DM version of this driver used to set BAR0 register after the
calls to pci_set_region.
I found out that for some strange reason the ath10k driver in kernel
fails to work if this is done the other way around.
I know that Linux's driver should not depend on how U-Boot does things,
but for some strange reason it does and this seems to be the simplest
solution. Fix it since it caused regressions on Omnia.

This patch adds a comment to explain the use of the hardcoded value for
the number of address cells in mvebu_get_tgt_attr(). This should help to
rework this function, once CONFIG_OF_LIVE is enabled for MVEBU in
general.

This patch adds DM_PCI support to the MVEBU PCIe driver. This is
necessary, since all PCI drivers have to be moved to DM (driver model)
until the v2019.07 release.
To not break git bisect'ablility, this patch also moves CONFIG_PCI_MVEBU
from config headers to the defconfig files.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

Armada 38x has four PCI ports, not three.
The optimization in pci_init_board() seems to assume that every port has
three lanes. This is obviously wrong, and breaks support for Armada 38x.

Armada XP has support for X4 lanes, boards specify this in their
serdes_cfg. During PEX init in high_speed_env_lib.c, the configuration
is stored in GEN_PURP_RES_2_REG.
When enumerating PEX, subsequent interfaces of an X4 lane must be
skipped. Otherwise the enumeration hangs up the board.
The way this is implemented here is not exactly beautiful, but it mimics
how Marvell's BSP does it. Alternatively we could get the information
using board_serdes_cfg_get(), but that won't lead to clean code, either.

This adds a PCI driver for the controllers found on Marvell MVEBU SoCs.
Besides the driver, this patch also removes the statically defined
PCI MBUS windows. As they are not needed anymore, since this PCIe
driver now creates the windows dynamically.
Tested on Armada XP db-mv784mp-gp eval board using an Intel E1000
PCIe card in all 3 PCIe slots. And on the Armada 38x db-88f6820-gp
eval board using this Intel E1000 PCIe card in the PCIe 0 slot.
This port was done in cooperation with Anton Schubert.
