3b7961a326 ASoC: atmel-i2s: Fix usage of capture and playback at the same time 
For both capture and playback streams to work at the same time, only the
needed values from a register need to be updated. Also, clocks should be
enabled only when the first stream is started and stopped when there is no
running stream.

The I2S needs to have the same sample bits for both capture and playback
streams.

f4bf1f4d13 ASoC: atmel-i2s: do not warn if muxclk is missing 
Besides the fact that muxclk is optional, muxclk can be set using
assigned-clocks, removing the need to set it in driver. The warning is
thus unneeded, so we can transform it in a debug print, eventually to just
reflect that muxclk was not set by the driver.

73ad0df572 ASoC: atmel-i2s: Remove unnecessary audio PLL clock (aclk) 
The generated clock (gclk) driver is able to set aclk as its parent and
change its rate alone, if needed. This means that our driver no longer
needs to configure aclk and we can let gclk select and configure its
clock source.
