The convention is that clk_get(dev, NULL) will get the bus clock
for the device and that any other clocks are appropriately named.

In the device tree case, the bus clock is first, and can generally
be named anything you like, such as "bus".

If the module does not have one, then you can always supply a dummy
clock.
