Marc Kleine-Budde b9f9cd0c62 can-calc-bit-timing: calculate bit timings for all known controllers by default 
When testing or improving the bit timing algorithm, you're probably
interested in the values of all can controllers. Further you might not
know the all reference clocks of the controllers.

This patch add a "ref_clock" member to the "struct can_bittiming_const"
that holds the reference clock of the controller in Hz.

By default now the bit timing is calculated for all known can
controllers with the default ref_clock defined in "can_bittiming_const".

It's still possible to overwrite the ref clock with the command line
option "-c".

Marc Kleine-Budde 26488b16e6 can-calc-bit-timing: improve printing of bit timing parameters 
This patch adds additional fields when printing the bit timing
parameters. Now the real bitrate the nominal and the real sample point
as well as the error of the sample point is displayed.

The output now looks like this:

Bit timing parameters for at91 with 100.000000 MHz ref clock

Marc Kleine-Budde ccd199739e can-calc-bit-timing: use algorithm from the kernel 
This patch copies the algorithm functions (can_update_spt and
can_calc_bittiming) from the kernel. Then some glue code is added that
these functions compile in userspace.
