drm/bridge: anx7625: Ensure bridge is suspended in disable()
Similar to commit 26db46bc9c67 ("drm/bridge: parade-ps8640: Ensure bridge
is suspended in .post_disable()"). Add a mutex to ensure that aux transfer
won't race with atomic_disable by holding the PM reference and prevent
the bridge from suspend.
Also we need to use pm_runtime_put_sync_suspend() to suspend the bridge
instead of idle with pm_runtime_put_sync().
Fixes: 3203e497eb76 ("drm/bridge: anx7625: Synchronously run runtime suspend.")
Fixes: adca62ec370c ("drm/bridge: anx7625: Support reading edid through aux channel")
