The dtpm table is used to let the different dtpm backends to register their setup callbacks in a single place and preventing to export multiple functions all around the kernel. That allows the dtpm code to be self-encapsulated. The dtpm hierarchy will be passed as a parameter by a platform specific code and that will lead to the creation of the different dtpm nodes. The function creating the hierarchy could be called from a module at init time or when it is loaded. However, at this moment the table is already freed as it belongs to the init section and the creation will lead to a invalid memory access. Fix this by moving the table to the data section.
