can: m_can: fix nominal bitiming tseg2 min for version >= 3.1
[ Upstream commit e3409e4192535fbcc86a84b7a65d9351f46039ec ]
At lest the revision 3.3.0 of the bosch m_can IP core specifies that valid
register values for "Nominal Time segment after sample point (NTSEG2)" are from
1 to 127. As the hardware uses a value of one more than the programmed value,
mean tseg2_min is 2.
This patch fixes the tseg2_min value accordingly.
