cxl: sparse: Silence iomem warning in debugfs file creation
An IO address, tagged with __iomem, is passed to debugfs_create_file
as private data. This requires that it be cast to void *. The cast
drops the __iomem annotation and so creates a sparse warning:
drivers/misc/cxl/debugfs.c:51:57: warning: cast removes address space of expression
The address space marker is added back in the file operations
(fops_io_u64).
Silence the warning with __force.
