ASoC: tlv320aic31xx: Make regmap cache only on probe()
Currently the tlv320aic31xx driver has regulator support but does not enable the regulators during probe, deferring this until something causes ASoC to make the card active. It does put the device into cache only mode but only when the component level probe is called, however if interrupts are in use the driver will access the regmap before then which if the regulators are not powered on would cause I/O problems.
