MFD: twl6040: Cache the vibra control registers

The vibra control register will be used from the ASoC codec driver as well.
In order to avoid latency issues caused by I2C read access, cache the two
control register within the core driver, so we do not need to reach out
to the chip to read it back.

ASoC: Remove redundant snd_soc_dapm_sync() calls from machine drivers

The core will sync DAPM as part of the card initialization, there is no
need for machine drivers to do so during their setup.

OMAP drivers are omitted as I know Peter already has patches for them.
