[PATCH v5 32/52] docs: basics.rst: get rid of rcu kernel-doc macros

[Mauro Carvalho Chehab]

        .../Documentation/driver-api/basics.rst: WARNING: Duplicate C 
declaration, also defined in 'core-api/kernel-api'.
        Declaration is 'rcu_idle_enter'.
        .../Documentation/driver-api/basics.rst: WARNING: Duplicate C 
declaration, also defined in 'core-api/kernel-api'.
        Declaration is 'rcu_idle_exit'.
        .../Documentation/driver-api/basics.rst: WARNING: Duplicate C 
declaration, also defined in 'core-api/kernel-api'.
        Declaration is 'rcu_is_watching'.
        .../Documentation/driver-api/basics.rst: WARNING: Duplicate C 
declaration, also defined in 'core-api/kernel-api'.
        Declaration is 'call_rcu'.
        .../Documentation/driver-api/basics.rst: WARNING: Duplicate C 
declaration, also defined in 'core-api/kernel-api'.
        Declaration is 'synchronize_rcu'.
        ...
