Subject: [PATCH v3 3/4] iplink_can: print brp and dbrp bittiming variables

Report the value of the bit-rate prescaler (brp) for both the nominal
and the data bittiming.

Currently, only the constant brp values (brp_{min,max,inc}) are being
reported. Also, brp is the only member of struct can_bittiming not
being reported.

Although brp is not used as an input for bittiming calculation, it
makes sense to output it.
