ASoC: da9055: Fix device registration of PMIC and CODEC devices
Currently the I2C device Ids conflict for the MFD and CODEC so cannot be both instantiated on one platform. This patch updates the Ids and names to make them unique from each other. It should be noted that the I2C addresses for both PMIC and CODEC are modifiable so instantiation of the two are kept as separate devices, rather than instantiating the CODEC from the MFD code.
