plat/arm: Rentroduce tb_fw_config device tree
Moved BL2 configuration nodes from fw_config to newly
created tb_fw_config device tree.
fw_config device tree's main usage is to hold properties shared
across all BLx images.
An example is the "dtb-registry" node, which contains the
information about the other device tree configurations
(load-address, size).
Also, Updated load-address of tb_fw_config which is now located
after fw_config in SRAM.
