Hsin-Yi Wang a2fa86e2bb drm/bridge: anx7625: Ensure bridge is suspended in disable()
[ Upstream commit 4d5b7daa3c610af3f322ad1e91fc0c752ff32f0e ]

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: 3203e497eb ("drm/bridge: anx7625: Synchronously run runtime suspend.")
Fixes: adca62ec37 ("drm/bridge: anx7625: Support reading edid through aux channel")
