The simple-card-util driver sends 0Hz frequency requests during stream
shutdown (change commit id 2458adb8f), which can request frequencies
lower than FMON (Frequency Monitor) minimum allowed rate.
For T264 AUD_MCLK, FMON sets minimum allowed clock frequency to 1.5MHz,
but 0Hz requests trigger BPMP to use its minimum rate
(clock parent rate / max clock divider) causing FMON fault logs:
verify_rate_range: FMON_AUD_MCLK: rate 383999 below min 1500000
fmon_update_config: FMON_AUD_MCLK: detected fault 0x80
Add ignore_zero_clk_rate_req flag to ignore these requests for Tegra
clocks.
