ASoC: tegra: tegra210: Use devm_clk_get_optional() for sync_input clock

The existing comment states that the sync_input clock is only needed
when another I/O is configured to use the current I2S instance as its
input clock, and the current code does not treat its absence as an
error.
Use devm_clk_get_optional() to match the existing behaviour while still
reporting real failures via dev_err_probe(). Update the comment to
describe the optional nature of the clock rather than the previous error
handling.
