arm-bsp: add support to cortex-a5 designstart

Browse Source 
Add tf-a recipes, u-boot, machine configuration, and documentation to
support Arm Cortex-A5 Designstart.

The output of this build is compatible to run on the FVP and
the FPGA implementation of the package.

# Cortex-A5 DesignStart A5DS Platform Support in meta-arm-platforms
## Howto Build and Run
### Configuration:
In the local.conf file, MACHINE should be set as follow:
MACHINE ?= "a5ds"
DISTRO ?= "iota-tiny"
Or set environment variables with that values:
MACHINE "a5ds"
DISTRO "iota-tiny"
### Build:
``bash$ bitbake iota-tiny-image```
### Run:
To run the result in a Fixed Virtual Platform please get:
https://git.linaro.org/landing-teams/working/arm/model-scripts
and follow the instructions in the readme.txt file in that
repository.

Subject: [PATCH] plat/arm: a5ds: move dtb to a new address
When Using bigger kernel images (>8.4MB compressed zImage) and at
decompress and final location init stage of kernel start makes it
override dtb at this address, to avoid this move the dtb a little
higher in address related.
