Commit dfd32cad146e ("dma-mapping: remove dma_zalloc_coherent()")
removed the definition of dma_zalloc_coherent() and also removed the
corresponding patch rule for replacing instances of dma_alloc_coherent +
memset in zalloc-simple.cocci (though left the report rule).
Add a new patch rule to remove unnecessary calls to memset after
allocating with dma_alloc_coherent. While we're at it, fix a couple of
typos.

dma_zalloc_coherent() is no longer needed as it has no users because
dma_alloc_coherent() already zeroes out memory for us.
The Coccinelle grammar rule that used to check for dma_alloc_coherent()
+ memset() is modified so that it just tells the user that the memset is
not needed anymore.

zalloc-simple.cocci
Because pci_alloc_consistent has been deprecated. We prefer to use
dma_alloc_coherent directly. Therefore, we should remove pci_alloc_consistent
to increase the confidence.

Rename kzalloc-simple to zalloc-simple since now the rule is not
specific to kzalloc function only, but also to many other zero memory
allocating functions specified in the rule.
