can: esd: add support for esd GmbH PCIe/402 CAN interface family

This patch adds support for the PCI based PCIe/402 CAN interface family
from esd GmbH that is available with various form factors
(https://esd.eu/en/products/402-series-can-interfaces).

All boards utilize a FPGA based CAN controller solution developed
by esd (esdACC). For more information on the esdACC see
https://esd.eu/en/products/esdacc.

This driver detects all available CAN interface board variants of
the family but atm. operates the CAN-FD capable devices in
Classic-CAN mode only! A later patch will introduce the CAN-FD
functionality in this driver.
