can: peak: Fix bittiming fields size in bits
This fixes the bitimings fields ranges supported by all the CAN-FD USB
interfaces of the PEAK-System CAN-FD adapters.
Very first development versions of the IP core API defined smaller TSGEx
and SJW fields for both nominal and data bittimings records than the
production versions. This patch fixes them by enlarging their sizes to
the actual values:
field: old size: fixed size:
nominal TSGEG1 6 8
nominal TSGEG2 4 7
nominal SJW 4 7
data TSGEG1 4 5
data TSGEG2 3 4
data SJW 2 4
Note that this has no other consequences than offering larger choice to
bitrate encoding.
