Add properties as per new bindings in zynqmp remoteproc node
to represent TCM address and size.

This patch also adds alternative remoteproc node to represent
remoteproc cluster in split mode. By default lockstep mode is
enabled and users should disable it before using split mode
dts. Both device-tree nodes can't be used simultaneously one
of them must be disabled. For zcu102-1.0 and zcu102-1.1 board
remoteproc split mode dts node is enabled and lockstep mode
dts is disabled.

Hi Michal,

Thanks for reviews. I will ping you once driver changes are approved.

Or Mathieu can take this in remoteproc tree, either way is fine.

But I would like to wait till driver changes are approved.

I'll pick this up with the rest of the driver.  It will be easier that way.

As far as I can tell, in lockstep mode the last two entries are not needed.
This is also contrasting with that is in the bindings, which is quite confusing.

Hi Mathieu,

Yes I agree. I think it should be same as of bindings example.

However, I will have to test and make sure no impact on driver. I will fix it in next revision.

Meanwhile, are you going to review driver changes as well or do you want to wait for next revision ?
