Fix DeprecationWarning for collections.abc
DeprecationWarning: Using or importing the ABCs from 'collections' instead of from 'collections.abc' is deprecated since Python 3.3, and in 3.9 it will stop working

Florent Kermarrec 35929c0f8a soc/integration/csr_bridge: use registered version only when SDRAM is present.
Seems to be a good compromise for now.

Gabriel Somlo ba34c85284 cores/dma, liblitesdcard/sdcard: use 64 bits for dma base address
Make the DMA base address register 64-bit wide, to cover situations
in which the physical memory being accessed is above the 4GB limit
(e.g., on 64-bit systems with more than 4GB of provisioned physical
memory).

Also update DMA reader/writer setup call sites in the bios (currently
only used by litesdcard).

Florent Kermarrec 6f69679d21 cpu/vexriscv_smp: more coherent_dma to __init__ instead of add_memory_buses.
LiteX is creating the SoC.dma_bus just after the CPU is declared, so declaring it in add_memory_buses was preventing it.
It's also more coherent to move it to __init__ since not related to the memory_buses.

Florent Kermarrec 00629c45b0 interconnect/csr: add CSR registers ordering support.
The original CSR registers ordering (big: MSB on lower addresses) is not convenient
when the SoC is interfaced with a real OS (for example as a PCIe add-on board or
with a CPU running Linux).

With this, the original ordering is kept as default (big), but it can now be switched
to little to avoid software workarounds in drivers and should probably be in the future
the default for PCIe/Linux SoCs.

Rocket's DMA slave interface (and/or internal routing) currently

above 25MHz (as tested on nexys4ddr, with Rocket, at 75MHz main

Gabriel Somlo d8161e5a86 integration/soc: make DMA slave region cover (at least) the lower 4GB
Assuming we currently support a 32-bit (4GB) physical address space,
ensure that the dma_bus slave covers the entire range, covering any
possible layout of the LiteX SoC memory map (e.g., rocket has MMIO
in a wide range of registers located below 2GB, and DRAM starting at
the 2GB mark, needing DMA accesses to be routed appropriately for the
entire 4GB physical address range).
