sequence makes booting more stable.

pci: pci_mvebu: Properly configure and use PCI Bridge (PCIe Root Port)

The mysterious "Memory controller" PCI device which is present in PCI
config space is improperly configured and crippled PCI Bridge which acts
as PCIe Root Port for endpoint PCIe card.

This PCI Bridge reports in PCI config space incorrect Class Code (Memory
Controller) and incorrect Header Type (Type 0). It looks like HW bug in
mvebu PCIe controller but apparently it can be changed via mvebu registers
to correct values.

The worst thing is that this PCI Bridge is crippled and its PCI config
registers in range 0x10-0x34 alias access to internal mvebu registers which
have different functionality as PCI Bridge registers. Moreover,
configuration of PCI primary and secondary bus numbers (registers 0x18
and 0x19) is done via totally different mvebu registers via totally strange
method and cannot be done via PCI Bridge config space.

Due to above fact about PCI config range 0x10-0x34, allocate a private
cfgcache[] buffer in the driver, to which PCI config access requests to
the 0x10-0x34 space will be redirected in mvebu_pcie_read_config() and
mvebu_pcie_write_config() functions. Function mvebu_pcie_write_config()
will also catch writes to PCI_PRIMARY_BUS (0x18) and PCI_SECONDARY_BUS
(0x19) registers and set PCI Bridge primary and secondary bus numbers via
mvebu's own method.

Also, Expansion ROM Base Address register (0x38) is available, but at
different offset 0x30. So recalculate register offset before accessing PCI
config space.

After these steps U-Boot sees working PCI Bridge and CONFIG_PCI_PNP code
can finally start enumerating all PCIe devices correctly, even with more
complicated PCI topology. So update also mvebu_pcie_valid_addr() function
to reflect state of the real device topology.

Each PCIe port is de-facto isolated and every PCI Bridge which is part of
PCIe Root Complex is also isolated, so put them on separate PCI buses as
(local) device 0.

U-Boot already supports enumerating separate PCI buses, real (HW) bus
number can be retrieved by "PCI_BUS(bdf) - dev_seq(bus)" code, so update
config read/write functions to properly handle more complicated tree
topologies (e.g. when a PCIe switch with multiple PCI buses is connected
to the PCIe port).

Local bus number and local device number on mvebu are used for determining
which config request type is used (Type 0 vs Type 1). On normal non-broken
PCIe hardware it is done by primary and secondary bus numbers. So correctly
translate settings between these numbers to ensure that correct config
requests are sent over the PCIe bus.

As bus numbers are correctly re-configured, it does not make sense to print
some initial bogus configuration during probe, so remove this debug code.

According to Nick Desaulniers:

"This is a known difference between GNU and LLVM linkers; the GNU
 linkers permit relocations in readonly segments (making them not read

Since U-Boot apparently seems to use relocations in readonly segments,
change the global linker flags to permit them when linking with LLD by
specifying '-z notext'.
