Since some driver like ohci, lcd used dcache functions. But some ARM

To avoid compiling errors this patch adds an weak empty stub function
for all ARM cpu.
And each cpu can implement its own implementation. If not implemented
by default it will use an empty function.

So, why exactly can't this be entirely common code , but a CPU-specific
code ? :)
Do you mean to make those empty functions as common code for all arch
cpu to use? It seems there is no place to put common code for all arch cpu.
