The MC13783 Chip Errata, Rev. 4 says, that depending on SPI clock
and main audio clock speed, the Audio Codec or Stereo DAC do sometimes
not start when programmed to do so. This is due to an internal clock
timing issue related to the loading of the SPI bits into the audio block.

On an i.MX27 based system, this issue lead to switched audio channels under
certain circumstances: RTC + Touch + Audio are used and loaded at startup.

The mentioned workaround of writing registers 40 and 41 two times is implemented
here.

The ssm2602 uses regmap for caching not soc-cache, so we need to use

The core will call snd_soc_dapm_new_widgets() once all components of the card
have been initialized, so there is no need to do this manually in the driver.
Calling it earlier also might result in a partially instantiated system being
powered up which cause undesired side effects.
