[PATCH 6/9] hw/arm/aspeed_ast10x0: Map HACE peripheral

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Since I don't have access to the datasheet, the relevant
values were found in:
https://github.com/AspeedTech-BMC/zephyr/blob/v00.01.08/dts/arm/aspeed/ast10x0.dtsi

Before on Zephyr:

  uart:~$ crypto aes256_cbc_vault
  aes256_cbc vault key 1
  [00:00:06.699,000] <inf> hace_global: aspeed_crypto_session_setup
  [00:00:06.699,000] <inf> hace_global: data->cmd: 1c2098
  [00:00:06.699,000] <inf> hace_global: crypto_data_src: 93340

  [00:00:06.699,000] <inf> hace_global: crypto_cmd_reg:  11c2098
  [00:00:09.743,000] <inf> hace_global: HACE_STS: 0
  [00:00:09.743,000] <err> hace_global: HACE poll timeout

  [00:00:09.743,000] <inf> hace_global: aspeed_crypto_session_free
  uart:~$

After:

  uart:~$ crypto aes256_cbc_vault
  aes256_cbc vault key 1
  Was waiting for:
  6b c1 be e2 2e 40 9f 96 e9 3d 7e 11 73 93 17 2a
  ae 2d 8a 57 1e 03 ac 9c 9e b7 6f ac 45 af 8e 51

  f6 9f 24 45 df 4f 9b 17 ad 2b 41 7b e6 6c 37 10

   But got:
  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
  00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

Should we rename HACE 'dram' as 'secram' / 'secure-ram'?
