feat(versal): retrieval of console information from dtb

Introduces functionality to retrieve console information from the
device tree (DTB) and use it in TF-A code.

Comparing early console information and the data populated from
the DTB. In case of a mistmatch, the changes 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.
