GFP_DMA does not guarantee that the returned memory is aligned
for DMA. In fact for sun8i-ss it is superfluous and can be removed.
However, kmalloc may start returning DMA-unaligned memory in future
so fix this by adding the alignment by hand.

The kfree_sensitive is a kernel API to clear sensitive information
that should not be leaked to other future users of the same memory
objects and free the memory. Its function is the same as the
combination of memzero_explicit and kfree. Thus, we can replace the
combination APIs with the single kfree_sensitive API.

In the case where the dma_iv mapping fails, the return error path leaks
the memory allocated to object d. Fix this by adding a new error return
label and jumping to this to ensure d is free'd before the return.

This patch had support for the PRNG present in the SS.
The output was tested with rngtest without any failure.
