rust: opp: Make the doctest example depend on CONFIG_OF

Browse Source 
The doctest example uses a function only available for CONFIG_OF and so
the build with doc tests fails when it isn't enabled.

  error[E0599]: no function or associated item named `from_of_cpumask`
  found for struct `rust_doctest_kernel_alloc_kbox_rs_4::kernel::opp::Table`
  in the current scope

Fix this by making the doctest depend on CONFIG_OF.
