[PATCH 2/4] drivers: media: i2c: imx471: Add vdig and vif power supplies

According to the product brief, the IMX471 sensor requires analog
(vana, 2.8V), digital (vdig, 1.05V), and interface (vif, 1.8V) power
supplies. Currently, only the analog supply is requested.

Add 'vdig' and 'vif' to the regulator supply array. Following the
pattern of other media i2c drivers (e.g., imx219, imx415), the regulator
core will automatically substitute dummy regulators if these are
missing.
