Since we're using designated initialisers for compat data, we should
use a completely empty initializer for the sentinel.

Remove "struct of_compat_data" and replace its usage with
"struct device_compatible_entry"; they are ABI-compatible.

Fix several "loses const qualifier" bugs encountered during
this conversion.

- set status for "analog_sound" to enabled.

and "rockchip,rk3288-i2s".

this gets i2s and ausoc to attach, but no audio(4) yet.

to complete this probably also needs a codec driver (appears
to be rk3328 specific, unlike eg pinebookpro's es8316), and
support for "audio-graph-card" type sound cards.

save the return value of fdtbus_clock_enable() so we can both
report it correctly instead of always 0, and also return failure
to the caller.

Remove rounding by 4 bytes on round_blocksize().
For drivers which supports only 16bit * 2channels sampling,
rounding by 4 bytes no longer meaningful.

Remove debug printfs

Add driver for Rockchip I2S/PCM controller.
