V4L/DVB (6633): xc2028: make register reads atomic
Issuing register reads as a separate address write and data read transactions
means that other I2C activity could occur in between and state could get out
of sync. Issue both the write and read in a single transaction so that the
i2c layer can prevent other users accessing the bus until we are complete.
