media: i2c: ar0521: Use the v4l2 helper for obtaining the clock 

devm_clk_get() fails on ACPI-based platforms, where firmware does not
provide a direct reference to the clock producer.

Replace devm_clk_get() with the new v4l2 helper devm_v4l2_sensor_clk_get()
that works on both DT- and ACPI-based platforms to retrieve a reference to
the clock producer from firmware.
