Defer root page table allocation and unify context init/fini functions.
Move allocation of the root page table from the file_priv_open function to
perform a lazy allocation approach during ivpu_bo_pin().
By doing so, we avoid the overhead of allocating page tables for simple
operations like GET_PARAM that do not require them.
Additionally, the MMU context descriptor table initialization has been
moved to the ivpu_mmu_context_map_page function.
This change streamlines the process and ensures that the descriptor table
is only initialized when it is actually needed.
Refactor init/fini functions to remove redundant code and make the context
management more straightforward.
Overall, these changes lead to a reduction in the time taken by the file
descriptor open operation, as the costly root page table allocation is now
avoided for operations that do not require it.
