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: 3203e497eb76 ("drm/bridge: anx7625: Synchronously run runtime suspend.")

drm/bridge: anx7625: Use uint8 for lane-swing arrays
As defined in the anx7625 dt-binding, the analogix,lane0-swing and
analogix,lane1-swing properties are uint8 arrays. Yet, the driver was
reading the array as if it were of uint32 and masking to 8-bit before
writing to the registers. This means that a devicetree written in
accordance to the dt-binding would have its values incorrectly parsed.
Fix the issue by reading the array as uint8 and storing them as uint8
internally, so that we can also drop the masking when writing the
registers.

1. panel is populated in devm_of_dp_aux_populate_ep_devices(), so move

2. Use pm runtime autosuspend since aux transfer function is called
multiple times when reading edid.
3. No-op if aux transfer length is 0.
