clock can from 16mhz xtal #5

Switch CAN0 clock source from the 48MHz bus clock to the 16MHz xtal clock. Update bit phase timings accordingly.

Report from pawelsky on the teensy forum:

Did some quick test @ 1M. Works fine with (24, 48, 72, 96, 120, 144 and 168 MHz). Did not try on 16, 8, 4 and 2 MHz as I'm using the USB serial which is disabled with these clock values. I have 3 filters enabled.

More alternate CPU clock testing from pawelsky indicates the CPU clock can be as low as 8 MHz. Any lower and it will not work reliably.

In addition CAN bus speed has also been confirmed at the other bit rates.
