staging: ste_rmi4: remove cross-dependent platform data
The ux500 machine was actually defining platform data for the staging driver ste_rmi4, which is not OK. Let us instead define some __weak platform data in the machine so that the staging driver can override it at compile-time and we can thus have the driver self-contained in staging.
