This patch fix compilation error and is an intermediate step
before the addition of DeviceTree support for newer targets.

seems like you're doing more than *just* fixing the build error. Which
build error do you get ?

clk_reset() is defined only in mach code which is not available in 
multi platform builds. But you are right, probably I have to mention
that some error messages are also changed. 

With this change driver will loss ability to reset PHY and LINk
controllers on newer targets, but I don't think it is functional 
on them right now (driver resources are not defined on these
boards). I am planing to add reset framework support to driver in
order to support them.

Ivan
