Now that the crc32c() library function directly takes advantage of
architecture-specific optimizations, it is unnecessary to go through the
crypto API. Just use crc32c(). This is much simpler, and it improves
performance due to eliminating the crypto API overhead.
Note that for crc32c the equivalent of crypto_shash_digest() is
cpu_to_le32(~crc32c(~0, ...)), considering that crypto_shash_digest()
had before and inversions as well as a cpu_to_le32() built-in. This
means that this driver is using u32 for fixed-endian types; this patch
does not try to fix that but rather just keep the exact same behavior.

On code inspection, there are many instances in the driver where
CEQE and AEQE fields written to by HW are read without guaranteeing
that the polarity bit has been read and checked first.
Add a read barrier to avoid reordering of loads on the CEQE/AEQE fields
prior to checking the polarity bit.
