juno: CDCEL clock driver uses incorrect address for I2C transaction

Created by: jimqui01

The first four bytes of the PLL Config register are not used by Juno, so we always skip them when reading/writing the PLL configuration. The address was not incremented for the write after a read when setting the PLL data in set_rate_from_index() call.
