ASoC: rsnd: src: Add missing scu_supply clock to suspend/resume
scu_supply is enabled alongside scu and scu_x2 during normal SRC
operation, but rsnd_src_suspend() and rsnd_src_resume() only disable
and re-enable scu and scu_x2. The supply clock is left enabled across
a system suspend and its prepare/enable refcount becomes unbalanced
after a suspend/resume cycle.
Disable scu_supply in rsnd_src_suspend() and re-enable it in
rsnd_src_resume() so the SRC clocks are managed consistently across
system PM transitions.
Fixes: ef19ecf042b4 ("ASoC: rsnd: Add system suspend/resume support")
