ASoC: rsnd: Add missing initialization of ADG req_rate
If the "clock-frequency" DT property is not found, req_rate is used
uninitialized, and the "audio_clkout" clock will be created with an
arbitrary clock rate.
This uninitialized kernel stack data may leak to userspace through
/sys/kernel/debug/clk/clk_summary, cfr. the value in the "rate" column:
clock enable_cnt prepare_cnt rate accuracy phase
