Subject: [PATCH] can: flexcan: change .tseg1_min value to 2 in bittiming const

Time Segment1(tseg1) is composed of Propagate Segment(prop_seg) and
Phase Segmeng1(phase_seg1). The range of Time Segment1(plus 2) is 2
up to 16 according to latest reference manual. That means the minimum
value of PROPSEG and PSEG1 bit field is 0. So change .tseg1 min value
to 2.
