Pass DBSC5 udevice and MODEMR0 register values to board specific
function dbsc5_get_board_data(). The board specific implementation
of dbsc5_get_board_data() can return struct renesas_dbsc5_board_config
which matches the board based on the content of MODEMR0 or content
of DT accessible via the udevice.
