[PATCH 2/2] drm: qxl: Remove unused debugfs code

[linux@treblig.org]

From: "Dr. David Alan Gilbert" <linux@treblig.org>

qxl_debugfs_add_files() has been unused since 2022's
commit d0719e09264b ("drm/qxl: Use TTM builtin resource manager debugfs
code")

Remove it.

This now leaves the debugfs_count and debugfs members of struct
qxl_device unused.  Remove them.

QXL_DEBUGFS_MAX_COMPONENTS was only used as the size of the debugfs[]
array.  Remove it.

Signed-off-by: Dr. David Alan Gilbert <linux@treblig.org>
