Currently, uniphier_bl2_mmap hard-codes the memory region needed for
loading other images.

Towards the goal of making this really position-independent, call
mmap_add_dynamic_region() before that region gets accessed.

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

Skipping SCP_BL2 image is just a temporary workaround. If on-chip SCP
needs to work, BL2 should load the SCP_BL2 image.

The codebase was using non-standard headers. It is needed to replace
them by the correct ones so that we can use the new libc headers.

Allow to handle GZIP-compressed images by giving FIP_GZIP=1 from the
command line.

- Images are GZIP-compressed, then packed into FIP.  If Trusted Board
  Boot is enabled, certificates are generated based on the compressed
  images.

- GZIP decompressor is linked into BL2 to decompress images at
  run-time.

In the next commit, I will have more usecases to get struct image_info
from image ID.  It is better to make a helper function at a different
layer.  I do not need the current uniphier_image_descs_fixup() since
the code is small enough to be squashed into the caller side.

UniPhier platform implements non-TF boot ROM.  Prior to the BL2-AT-EL3
support, BL1 (worked as a pseudo ROM) was needed just for ensuring BL2
is entered at EL1-S.  Now, this platform is able to avoid this waste.

Enable the BL2_AT_EL3 option, and remove BL1.

Initial commit for Socionext UniPhier SoC support.  BL1, Bl2, and
BL31 are supported.  Refer to docs/plat/socionext-uniphier.md for
more detais.
