Currently both error code paths handled in dal_gpio_open_ex() issues
ASSERT_CRITICAL(), and this leads to a kernel panic unnecessarily if
CONFIG_KGDB is enabled. Since basically both are non-critical errors
and can be recovered, drop those assert calls and use a safer one,
BREAK_TO_DEBUGGER(), for allowing the debugging, instead.

[why]
dc_destroy should only clean up SW, this is because GPUs may be
removed before driver unload, leading to HW to be unavailable.
[how]
remove GPIO close as part of GPIO destroy, this is unnecessary because
GPIO is not shared, and GPIOs are generally closed after being opened
Add tracking to HW access during destructor to make future issues
easier to pinpoint, and block access to prevent hangs.

[why]
if dynamic allocation fails during gpio_open, it will cause crash due to
page fault.
[how]
handle allocation when gpio object gets created and prevent from calling
gpio_open if allocation failed

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.
