soundwire: generic_bandwidth_allocation: check required freq accurately

Currently, we check curr_dr_freq roughly by "if (curr_dr_freq <=
bus->params.bandwidth)" in sdw_compute_bus_params() and check it
accurately in sdw_select_row_col(). It works if we only support one
freq. But, we need to check it accurately in sdw_select_row_col() to
give it a chance to use a higher freq or use multi-lane.
