u-boot-aspeed: SHA512 backport and FIT bugfixes

These patches bring SHA512 support to the FIT in u-boot, SPL and
mkimage. The majority of the feature comes in with "Add support for
SHA384 and SHA512", while the rest are relevant bugfixes that have been
made to master since v2019.04.

There is not yet a change to the configuration to enable the new
algorithm and therefore only a minor image size change (an increase of
247 bytes due to "image: Check hash-nodes when checking configurations").

Harald Seiler (1):
      common: hash: Remove a debug printf statement

Heinrich Schuchardt (1):
      image-fit: fit_check_format check for valid FDT

Joel Stanley (1):
      ast2600: spl: Include RAM loader in BL2 ifdef

Patrick Doyle (1):
      rsa: reject images with unknown padding

Reuben Dowle (1):
      Add support for SHA384 and SHA512

Simon Glass (3):
      image: Be a little more verbose when checking signatures
      image: Return an error message from fit_config_verify_sig()
      image: Check hash-nodes when checking configurations
