ASoC: cs42l42: Wait at least 150us after writing SCLK_PRESENT

Browse source

There must be a delay of at least 150us after writing SCLK_PRESENT
before issuing another I2C write.

This is done using struct reg_sequence because it can specify a delay
after the write and the whole sequence is written atomically.
