misc: keba: Add basic KEBA CP500 system FPGA support
The KEBA CP500 system FPGA is a PCIe device, which consists of multiple
IP cores. Every IP core has its own auxiliary driver. The cp500 driver
registers an auxiliary device for each device and the corresponding
drivers are loaded by the Linux driver infrastructure.
Currently 3 variants of this device exists. Every variant has its own
PCI device ID, which is used to determine the list of available IP
cores. In this first version only the auxiliary device for the I2C
controller is registered.
Besides the auxiliary device registration some other basic functions of
the FPGA are implemented; e.g, FPGA version sysfs file, keep FPGA
configuration on reset sysfs file, error message for errors on the
internal AXI bus of the FPGA.
