media: si2168: Fix i2c command timeout on embedded platforms

On many embedded platforms i2c responses through USB are not returned
as quickly, plus constantly banging on the i2c master receive essentially
deadlocks the driver. Inserting a 3ms delay between i2c receive calls
and extending the timeout fixes all tested platforms.
