refactor(xilinx): create generic function for clock retrieval
Refactors the code in the AMD-Xilinx platform for Versal and Versal NET
to create a more generic function for obtaining clock signals
from the platform. The new function get_uart_clk is specific to each
platform and providing greater flexibility for clock signal retrieval
in various parts of the codebase.
