Introduces functionality to retrieve console information from the device tree (DTB) and use it in TF-A code. With fdt_get_stdout_node_offset() function, which reads the 'secure-chosen' first,'chosen' and 'stdout-path' properties from the DTB, providing a convenient and standardized way to access serial console information. Implemented a comparison mechanism between early console information and the data populated from the DTB. In case of a mismatch, the commit takes care of unregistering the build-time console configuration and registering the DTB-based console. Reorganizes the console configuration setup in BL31 by moving it to a dedicated function called setup_console() in the plat_console.c file. This change improves code readability by isolating console-related settings, making it easier to manage and extend the console configuration in the future.
