drm/imagination: Removed unused functions in pvr_fw_trace

Fixing the warning below due to an unused file level vtable. Removing
only this causes additional warnings for the now unused functions, so
I've removed those too.

>> drivers/gpu/drm/imagination/pvr_fw_trace.c:205:37: warning: 'pvr_fw_trace_group_mask_fops' defined but not used [-Wunused-const-variable=]
     205 | static const struct file_operations pvr_fw_trace_group_mask_fops = {
         |                                     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

Changes since v1:
- Corrected hash in Fixes tag.
