powerpc/mpc85xx: use correct dma compatible for several SoCs

Newer qoriq socs have an updated dma ip block with a
different compatible. Let's make sure we use the proper
string so that the dmas get their liodn.
In order to have the means to specify the compatible
string, the liodn setting macros were updated to receive
a new parameter for it.
The following SoCs were changed to use the new compatible:
 T1023/4, T1040, T2080/1, T4240, B4860.
