Drop use of the deprecated drmP.h from display/dc/os_types.h
Fix all fallout after this change.
Most of the fixes was adding a missing include of vmalloc.h.

[Why]
When querying HPD via GPIO flow,
it will create a new gpio object then free in the end of query.
There is a irql issue for HPD querying at ISR level.
[How]
Therefore, creating the HPD gpio object in dc_link and set it as unlcok in default.
1. reducing unnecessary malloc/free when HPD querying.
2. reducing init GPIO flow.
3. add lock/unlock to prevent multi gpio service running.
