ASoC: meson: aiu: introduce a struct for platform specific information
Introduce a struct aiu_platform_data to make the driver aware of platform specific information. Convert the existing check for the internal stereo audio codec (only available on GXL) to this new struct. Support for the 32-bit SoCs will need this as well because the AIU_CLK_CTRL_MORE register doesn't have the I2S divider bits (and we need to use the I2S divider from AIU_CLK_CTRL instead).
