OMAP4: PMIC: Add support for twl6030 codec

In order to have TWL6030 CODEC driver as a platform driver, codec data
should be passed through twl_platform_data structure.

For twl6030 audio codec, the following data may be passed:
    - audpwron_gpio: gpio line used to power-up/down the codec. A low-to-high
      transition powers codec up. Setting audpwron_gpio to a negative value
      means that codec will use manual power sequence instead of automatic
      sequence
    - naudint_irq: irq line for audio interrupt. twl6030 drives NAUDINT line
      to low when an interrupt (codec ready, plug insertion/removal, etc) is
      detected

However, codec driver can operate if any or none of them are passed.
