The purpose of this patch is to introduce a new CAN driver to support
the esd GmbH 402 family of CAN interface boards. The hardware design
is based on a CAN controller implemented in a FPGA attached to a
PCIe link.

More information on these boards can be found following the links
included in the commit message.

This patch supports all boards but will operate the CAN-FD capable
boards only in Classic-CAN mode. The CAN-FD support will be added
when the initial patch has stabilized.

The patch is based on the linux-can-next testing branch.

The patch is uses the previous work of my former colleague:

*Note*: scripts/ still emits the following warnings:
1.esd402_pci.c:293: Still prints the non-hashed virtual address for
  debug purposes with pci_err(). This is done only on fatal
  initialization failure during modprobe and seems sensible in this
  case to debug the error. This will never occur in normal operation.
2.esdacc.h:269: The irq_cnt pointer is still declared volatile and
  this has a reason and is explained in detail in the header
  referencing the exception noted in volatile-considered-harmful.rst.
