Aspeed Hash and Crypto Engine (HACE) is designed to accelerate the
throughput of hash data digest, encryption and decryption.

These patches aim to add Aspeed hash & crypto driver support.
The hash & crypto driver also pass the run-time self tests that
take place at algorithm registration.

The patch series are tested on both AST2500 & AST2600 evaluation boards.

Tested-by below configs:
- CONFIG_CRYPTO_MANAGER_DISABLE_TESTS is not set
- CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y
- CONFIG_DMA_API_DEBUG=y
- CONFIG_DMA_API_DEBUG_SG=y
- CONFIG_CPU_BIG_ENDIAN=y

Change since v9:
- Fix unnecessary "goto xxx".

Change since v8:
- Remove __weak functions for register/unregister crypto algos.
- Add missing functions of unregister crypto algos.
- Use single debug config to control debug messages.

Change since v7:
- Define debug Kconfigs.
- Simplify assign iv/ivsize.
- Simplify cra_init() for hmac related init.

Change since v6:
- Refine debug print.
- Change aspeed_sg_list struct memeber's type to __le32.

Change since v5:
- Re-define HACE clock define to fix breaking ABI.

Change since v4:
- Add AST2500 clock definition & dts node.
- Add software fallback for handling corner cases.
- Fix copy wrong key length.

Change since v3:
- Use dmam_alloc_coherent() instead to manage dma_alloc_coherent().
- Add more error handler of dma_prepare() & crypto_engine_start().

Change since v2:
- Fix endianness issue. Tested on both little endian & big endian
  system.
- Use common crypto hardware engine for enqueue & dequeue requests.
- Use pre-defined IVs for SHA-family.
- Revise error handler flow.
- Fix sorts of coding style problems.

Change since v1:
- Add more error handlers, including DMA memory allocate/free, DMA
  map/unmap, clock enable/disable, etc.
- Fix check dma_map error for config DMA_API_DEBUG.
- Fix dt-binding doc & dts node naming.
