ASoC: cs42l83: Extend CS42L42 support to new part 

The CS42L83 part is a headphone jack codec found in recent Apple
machines. It is a publicly undocumented part but as far as can be told
it is identical to CS42L42 except for two points:

 * The chip ID is different.

 * Of those registers for which we have a default value in the existing
   CS42L42 kernel driver, one register (MCLK_CTL) differs in its reset
   value on CS42L83.

To address those two points (and only those), add to the CS42L42 driver
a separate CS42L83 front.
