drm/amd/display: Fix new dmub notification enabling in DM

Browse source

[Why]
Changes from "Fix for dmub outbox notification enable" need to land
in DM or DMUB outbox notification would be disabled.

[How]
Enable outbox notification only after interrupt are enabled and IRQ
handlers registered. Any pending notification will be sent by DMUB
once outbox notification is enabled.
