can: peak: Add support for new PCIe/M2 CAN FD interfaces

This adds support for the following PEAK-System CAN FD interfaces:

PCAN-cPCIe FD         CAN FD Interface for cPCI Serial (2 or 4 channels)
PCAN-PCIe/104-Express CAN FD Interface for PCIe/104-Express (1, 2 or 4 ch.)
PCAN-miniPCIe FD      CAN FD Interface for PCIe Mini (1, 2 or 4 channels)
PCAN-PCIe FD OEM      CAN FD Interface for PCIe OEM version (1, 2 or 4 ch.)
PCAN-M.2              CAN FD Interface for M.2 (1 or 2 channels)

Like the PCAN-PCIe FD interface, all of these boards run the same IP Core
that is able to handle CAN FD (see also http://www.peak-system.com).
