drm/xe: Remove unused functions

xe_bo_create_from_data() last use was removed in 2023 by
commit 0e1a47fcabc8 ("drm/xe: Add a helper for DRM device-lifetime BO
create")

xe_rtp_match_first_gslice_fused_off() last use was removed in 2023 by
commit 4e124151fcfc ("drm/xe/dg2: Drop pre-production workarounds")

Remove them, and xe_dss_mask_empty whose last use was by
xe_rtp_match_first_gslice_fused_off().

(Xe has a bunch ofother symbols that have been added but not used,
given how new it is, I've left those, as opposed to these that
had the code that used them removed).
