[PATCH 6/9] ASoC: SOF: imx8: make imx8_ops_init() an util function

[Laurentiu Mihalcea <laurentiumihalcea111@gmail.com>]

From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>

The definition for the ops_init() operation is similar among the imx8
chips (namely: imx8, imx8x, imx8m, and imx8ulp). The only difference is
the name of the 'struct snd_soc_dai_driver' array used to fill the SOF
ops structure.

As such, 'imx8_ops_init()' can be made into an utility function that takes
the 'struct snd_soc_dai_driver' array and its size as parameters and fills
the SOF ops structure fields accordingly. This will allow us to reuse this
function when the other drivers (imx8m, imx8ulp) are merged into this one.

Since the definition of the function is changed, it can no longer be
used directly by the SOF core. Therefore, also introduce a wrapper:
'imx_ops_init()' that will call 'imx8_ops_init()' with the right
parameters based on the chip.
