[PATCH 5.15 152/167] Revert "can: xilinx_can: Limit CANFD brp to 2"
From: Greg Kroah-Hartman

[ Upstream commit c6da4590fe819dfe28a4f8037a8dc1e056542fb4 ]
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.
