ASoC: simple-card-utils: add sysclk ordering support
When simple-audio-card programs sysclk for CPU and codec DAIs during
hw_params, the ordering of these calls may matter on some platforms.
Some CPU DAIs finalize or adjust the MCLK rate as part of their
set_sysclk() callback (for example by calling clk_set_rate()). If the
codec sysclk is configured before the CPU DAI applies the final MCLK
rate, the codec may configure its internal clocking based on a
non-final MCLK value.
Such situations can arise depending on the clock provider/consumer
relationship between the CPU DAI and the codec.
Introduce an explicit sysclk ordering enum in simple-card-utils and use
it to control the order of snd_soc_dai_set_sysclk() calls in the mclk-fs
handling path. The default behaviour remains unchanged (codec-first)
to avoid regressions.
