[PATCH 06/10] hwmon: (mcp3021) Drop platform data support

[Guenter Roeck <linux@roeck-us.net>]

No in-tree boards supply platform data to the mcp3021 driver. Reference
voltage is already configurable via the "reference-voltage-microvolt"
devicetree property, defaulting to 3300 mV otherwise.

Drop platform data handling from mcp3021_probe().
