The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_SDRAM
namespace do not easily transition to Kconfig. In many cases they likely
should come from the device tree instead. Move these out of CONFIG

uclass_first_device/uclass_next_device return value will be removed,
don't use it.
With the current implementation dev is equivalent to !ret. It is
redundant to check both, ret check can be replaced with dev check, and
ret check inside the iteration is dead code.

When there is no PCI bus uclass_first_device will return no bus and no
error which will result in pci_find_first_device calling
skip_to_next_device with no bus, and the bus is only checked at the end
of the while cycle, not the beginning.

PCIe config space has address range 0-4095. So do not allow reading from
addresses outside of this range. Lot of U-Boot drivers do not expect that
passed value is not in this range. PCI DM read function is extended to
fill read value to all ones or zeros when it fails as U-Boot callers
ignores return value.
Calling U-Boot command 'pci display.b 0.0.0 0 0x2000' now stops printing
config space at the end (before 0x1000 address).

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

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.

If vpcie-supply is defined by device-tree use that if
CONFIG_PCIE_IMX_POWER_GPIO is not defined.
Note that after this the following boards which define
CONFIG_PCIE_IMX_POWER_GPIO in their board header file as well as their
device-tree should be able to remove CONFIG_PCIE_IMX_PERST_GPIO without
consequence:
- mx6sabresd
- mx6sxsabresd
- novena
Note that the ge_bx50v3 board uses CONFIG_PCIE_IMX_POWER_GPIO and does
not have vpcie-supply defined in it's pcie node in the dt thus removing
CONFIG_PCIE_IMX_POWER_GPIO globally can't be done until that board adds
vpcie-supply.

Writing to the PCI_PRIMARY_BUS register of the root port should not change
bus number on which is root port present.
This PCI_PRIMARY_BUS register is used only for correct configuration of
legacy PCI stuff, like forwarding of PCI special cycles between buses.
Aardvark HW does not support PCI special cycles, so it does not have HW
register for PCI_PRIMARY_BUS and therefore it does not matter what is
stored in this register.
So fix this issue and do not use PCI_PRIMARY_BUS register in pci-aardvark.c
driver for moving root bus of the root port.
After this change there is no reason for storing bus number (zero) into
first_busno variable, so remove this variable.
