Subject: [PATCH V2 1/2] Revert "can: xilinx_can: Limit CANFD brp to 2"

This reverts commit 05ca14fdb6fe65614e0652d03e44b02748d25af7.

On early silicon engineering samples observed
bit shrinking issue when we use brp as 1.
Hence updated brp_min as 2. As in production
silicon this issue is fixed,so reverting the patch.
