The patch is to add all available dt clock nodes for babbage board.
It sticks to the clock name used in clock-mx51-mx53.c, so that
everything gets consistent to Reference Manual. For example, the
numbering in clock name usually starts from 1, while 'reg' property
numbering starts from 0 to easy clock binding.
Besides the generally used clock bindings, the following properties
are proposed in this patch.
* clock-source
This property is added to reflect the parent clock.
* clock-depend
The mxc 'struct clk' has the member 'secondary' to refer to the clock
that the 'clk' has dependency on. This 'secondary' clock needs to be
turned on whenever the 'clk' is turned on. This clock-depend property
is defined to reflect this 'secondary' clock.
