The d_can0/1 module integrated with AM335x device, requires
only one clock (fck) and driver expects clock to be available
without specifying any connection id (con_id) -
clk_get(&pdev->dev, NULL);
This is acceptable as module has only one clock and platform
code should respect this request, so create new clock nodes
inside am33xx clock-tree table based on dev_id and "con_id = NULL"
for both d_can0 and d_can1 instances.

This patch is boot tested on BeagleBone platform, and checked for
clk_get() api return value.
