Subject: drm/mediatek: dp: Use devm variant of drm_bridge_add()
Git-commit: 214a0944e6641319dd0df9c9fe61755a908bfd4e
Patch-mainline: v6.6-rc1
References: jsc#PED-3527 jsc#PED-5475 jsc#PED-6068 jsc#PED-6070 jsc#PED-6116 jsc#PED-6120 jsc#PED-5065 jsc#PED-5477 jsc#PED-5511 jsc#PED-6041 jsc#PED-6069 jsc#PED-6071
In preparation for adding support for aux-bus, which will add a code
path that may fail after the drm_bridge_add() call, change that to
devm_drm_bridge_add() to simplify failure paths later.
