dfd32cad14 dma-mapping: remove dma_zalloc_coherent() 
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.

6fbd856950 Coccinelle: remove pci_alloc_consistent semantic to detect in 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.

1936f8f300 Coccinelle: kzalloc-simple: Rename kzalloc-simple to zalloc-simple 
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.
