[PATCH 58/66] drm/amd/display: Adjust dmub outbox notification enable

[Qingqing Zhuo]

From: Meenakshikumar Somasundaram <meenakshikumar.somasundaram at amd.com>

[Why]
Currently driver enables dmub outbox notification before oubox ISR is
registered. During boot scenario, sometimes dmub issues hpd outbox
message before driver registers ISR and those messages are missed.

[How]
Enable dmub outbox notification after outbox ISR is registered. Also,
restructured outbox enable code to call from dm layer and renamed APIs.
