[PATCH 2/2] can: sja1000: of: add compatibility with Technologic Systems version

Technologic Systems provides an IP compatible with the SJA1000, instantiated in an FPGA. Because of some bus widths issue, access to registers is made through a "window" that works like this: base + 0x0: address to read/write base + 0x2: 8-bit register value This commit adds a new compati
