ISP is a child device to GFX, and its device specific information
is not available in ACPI. Adding the 2 GPIO resources required for
ISP_v4_1_1 in amdgpu_isp driver.

- GPIO 0 to allow sensor driver to enable and disable sensor module.
- GPIO 85 to allow ISP driver to enable and disable ISP RGB streaming mode.

In VM debug mode, it is desirable to notify the application
to correct the freeing sequence by unmapping the memory before
destroying the userptr in the old userptr path. Add a bitmask
to decide whether to send gpu vm fault to the applition.

<content type='text'>
This reverts commit 3a9626c816db901def438dc2513622e281186d39.

This breaks S4 because we end up setting the s3/s0ix flags
even when we are entering s4 since prepare is used by both
flows.  The causes both the S3/s0ix and s4 flags to be set
which breaks several checks in the driver which assume they
are mutually exclusive.

Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/3634

Replace disable_kq parameter with user_queue parameter.
The parameter has the following logic:
 -1 = auto (ASIC specific default)
  0 = user queues disabled
  1 = user queues enabled and kernel queues enabled (if supported)
  2 = user queues enabled and kernel queues disabled

The default behavior (-1) is currently the same as 0 for current
ASICs.  To enable user queues (in addition to kernel queues) set
user_queue=1. To enable user queues and disable kernel queues
(to make all resources available to user queues), set user_queue=2.

Switch from a bool to an enum and allow more options
for enforce isolation.  There are now 3 modes of operation:
- Disabled (0)
- Enabled (serialization and cleaner shader) (1)
- Enabled in legacy mode (no serialization or cleaner shader) (2)
This provides better flexibility for more use cases.
