rcu: Remove SPARSE_RCU_POINTER Kconfig option

Browse Source 
The sparse-based checking for non-RCU accesses to RCU-protected pointers
has been around for a very long time, and it is now the only type of
sparse-based checking that is optional.  This commit therefore makes
it unconditional.

This feature enables the __rcu sparse annotation for
RCU-protected pointers. This annotation will cause sparse
to flag any non-RCU used of annotated pointers. This can be
helpful when debugging RCU usage. Please note that this feature
is not intended to enforce code cleanliness; it is instead merely
a debugging aid.
Say Y to make sparse flag questionable use of RCU-protected pointers
Say N if you are unsure.
