samv7: fix CAN FD configuration

Browse Source 
Larger RX/TX buffers might be required for both FD and FD_BSW modes.
Default bit timing values are also changed since the original ones
did not provide correct results for default SAMv7 board clock selection
(150 MHz clock frequency). The current values provide correct bit timing
with sample point as close to 87.5 %.
