ASoC: TWL4030: Optimize the power up sequence
Since the reg cache now contains the chip default values for all registers (REG_OPTION is reset to it's default within this patch), there is no longer need to rewrite _all_ registers. Initialize only few selected registers. According to the latest information, the offset cancellation need to be done only once, when the codec is powered on, so there is no need for the power up wrapper. Move all chip initialization code under chip_init, and do it when the codec is initialized.
