Subject: [PATCH v2 5/5] can: xilinx_can: Fix the data phase btr1 calculation

From: Srinivas Neeli <srinivas.neeli@...inx.com>

While calculating bitrate for the data phase, the driver is using phase
segment 1 of the arbitration phase instead of the data phase.

Fixes: c223da6 ("can: xilinx_can: Add support for CANFD FD frames")
