feat(zynqmp): retrieval of console information from dtb

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.
