staging: android: binder: move to the "real" part of the kernel

The Android binder code has been "stable" for many years now.  No matter
what comes in the future, we are going to have to support this API, so
might as well move it to the "real" part of the kernel as there's no
real work that needs to be done to the existing code.

+	  Binder is used in Android for both communication between processes,
+	  and remote method invocation.
+
+	  This means one Android process can call a method/routine in another
+	  Android process, using Binder to identify, invoke and pass arguments
+	  between said processes.

+	  The Binder API has been changed to support both 32 and 64bit
+	  applications in a mixed environment.
+
+	  Enable this to support an old 32-bit Android user-space (v4.4 and
+	  earlier).
+
+	  Note that enabling this will break newer Android user-space.
