ASoC: fsl_rpmsg: Remove SET_SYSTEM_SLEEP_PM_OPS callback
For sound need to be continuously output at suspend with rpmsg
sound card, so need to keep the clock always on at suspend,
then suspend & resume callback is not needed.

ASoC: fsl_rpmsg: Add rpmsg audio support for i.MX8ULP
On i.MX8ULP the audio interface and codec are controlled
by Cortex-M domain, Cortex-M core provides audio service
over rpmsg.

The rpmsg audio function is almost same as i.MX7ULP
platform, so share same configuration.

ASoC: fsl_rpmsg: add soc specific data structure
Each platform has different supported rates and
formats, so add soc specific data for each platform.
This soc specific data is attached with compatible string.

ASoC: fsl_rpmsg: Check -EPROBE_DEFER for getting clocks
The devm_clk_get() may return -EPROBE_DEFER, then clocks
will be assigned to NULL wrongly. As the clocks are
optional so we can use devm_clk_get_optional() instead of
devm_clk_get().

ASoC: fsl_rpmsg: Add CPU DAI driver for audio base on rpmsg
This is a cpu dai driver for rpmsg audio use case,
which is mainly used for getting the user's configuration
from devicetree and configure the clocks which is used by
Cortex-M core.
