[PATCH 1/3] ASoC: da7219: Move required devm_* allocations to device level code

[Adam Thomson <Adam.Thomson.Opensource@diasemi.com>]

In preparation for cleanup of device level and codec level probe
funcitonality, all necessary devm_* allocations and fw retrieval
functions are moved to the I2C probe level code.
