Add the Infineon PEB2466 codec support 

Merge series from Herve Codina <herve.codina@bootlin.com>:

The Infineon PEB2466 codec is a programmable DSP-based four channels
codec with filters capabilities.
It also provides signals as GPIOs.

description: |

  The Infineon PEB2466 codec is a programmable DSP-based four channels codec

  with filters capabilities.



  The time-slots used by the codec must be set and so, the properties

  'dai-tdm-slot-num', 'dai-tdm-slot-width', 'dai-tdm-slot-tx-mask' and

  'dai-tdm-slot-rx-mask' must be present in the sound card node for sub-nodes

  that involve the codec. The codec uses one 8bit time-slot per channel.

  'dai-tdm-tdm-slot-with' must be set to 8.



  The PEB2466 codec also supports 28 gpios (signaling pins).
