IMU is a new firmware for GFX11.

There are four means by which firmware version can be queried
from the driver: device attributes, vf2pf, debugfs,
and the AMDGPU_INFO_FW_VERSION option in the amdgpu info ioctl.

Add IMU as an option for those four methods.

V2: Added debugfs

mode. This breaks amdgpu in Xen dom0 with message like this:

    [drm:dc_dmub_srv_wait_idle [amdgpu]] *ERROR* Error waiting for DMUB idle: status=3

While the reason for this failure is unclear, the passthrough mode is
not really necessary in Xen dom0 anyway. So, to unbreak booting affected
kernels, disable passthrough mode in this case.

These static variables save the RLC Scratch registers address.
When we install multiple GPUs (for example: XGMI setting) and
multiple GPUs call the function at same time. The RLC Scratch
registers address are changed each other. Then it caused
reading/writing from/to wrong GPU.

Removed the static from the variables. The variables are

after gmc sw init to reserve bad pages as early as possible.

called multiple times without re-initializing the work item.

inside early init to initialize the work item, afterwards call
