fconf: Add dynamic config DTBs info as property This patch introduces a better separation between the trusted-boot related properties, and the dynamic configuration DTBs loading information. The dynamic configuration DTBs properties are moved to a new node: `dtb-registry`. All the sub-nodes present will be provided to the dynamic config framework to be loaded. The node currently only contains the already defined configuration DTBs, but can be extended for future features if necessary. The dynamic config framework is modified to use the abstraction provided by the fconf framework, instead of directly accessing the DTBs. The trusted-boot properties are kept under the "arm,tb_fw" compatible string, but in a separate `tb_fw-config` node. The `tb_fw-config` property of the `dtb-registry` node simply points to the load address of `fw_config`, as the `tb_fw-config` is currently part of the same DTB.

lib/fconf: Update data type of config max size Update the data type of the member 'config_max_size' present in the structure 'dyn_cfg_dtb_info_t' to uint32_t. This change is being done so that dyn_cfg_dtb_info_t and image_info structure should use same data type for maximum size.

lib/fconf: Update 'set_fw_config_info' function Updated the function 'set_fw_config_info' to make it generic by doing below changes: 1. Rename function name from 'set_fw_config_info' to 'set_config_info' 2. Take image_id as an argument so that this function can set any config information.

plat/arm: Load and populate fw_config and tb_fw_config Modified the code to do below changes: 1. Load tb_fw_config along with fw_config by BL1. 2. Populate fw_config device tree information in the BL1 to load tb_fw_config. 3. In BL2, populate fw_config information to retrieve the address of tb_fw_config and then tb_fw_config gets populated using retrieved address. 4. Avoid processing of configuration file in case of error value returned from "fw_config_load" function. 5. Updated entrypoint information for BL2 image so that it's arg0 should point to fw_config address.
