Now that there's a function that calculates the SHA-256 digest of a
buffer in one step, use it instead of sha256_init() + sha256_update() +
sha256_final().
Also simplify the code by inlining calculate_sha256() into its caller
and switching a debug log statement to use %*phN instead of bin2hex().

Due to the fact that the x86 port does not support allocating objects
on the stack with an alignment that exceeds 8 bytes, we have a rather
ugly hack in the x86 code for ChaCha to ensure that the state array is
aligned to 16 bytes, allowing the SSE3 implementation of the algorithm
to use aligned loads.
Given that the performance benefit of using of aligned loads appears to
be limited (~0.25% for 1k blocks using tcrypt on a Corei7-8650U), and
the fact that this hack has leaked into generic ChaCha code, let's just
remove it.

The AmLogic GXL crypto accelerator driver is built into the kernel if
ARCH_MESON is set. However, given the single image policy of arm64, its
defconfig enables all platforms by default, and so ARCH_MESON is usually
enabled.
This means that the AmLogic driver causes the arm64 defconfig build to
pull in a huge chunk of the crypto stack as a builtin as well, which is
undesirable, so let's make the amlogic GXL driver default to 'm' instead.

There are two ways to implement SIMD accelerated GCM on arm64:
- using the PMULL instructions for carryless 64x64->128 multiplication,
in which case the architecture guarantees that the AES instructions are
available as well, and so we can use the AEAD implementation that combines
both,
- using the PMULL instructions for carryless 8x8->16 bit multiplication,
which is implemented as a shash, and can be combined with any ctr(aes)
implementation by the generic GCM AEAD template driver.
So let's drop the 64x64->128 shash driver, which is never needed for GCM,
and not suitable for use anywhere else.

First, I removed the trailing comma in the PRECOMPUTE line.
Second, I substituted:
1. GHASH_4_ENCRYPT_4_PARALLEL_DEC -> GHASH_4_ENCRYPT_4_PARALLEL_dec
2. GHASH_4_ENCRYPT_4_PARALLEL_ENC -> GHASH_4_ENCRYPT_4_PARALLEL_enc

I confirmed that this works with Linux-kernel v5.7.5 final.
