There are two scenarios:
1. The request comes from the DSP side (afaik for video use case), the
change should be in the DSP side binaries to request some other gpt
instead. I don't know how possible is to get this changed.
2. bridge driver also requests gpt8 whenever a mmu fault is triggered,
this to set a timer to interrupt the dsp after the mmu fault dump has
been finished, I think this can be easily replaced in bridge to use some
other gpt, but "1" is still there. (besides a new patch is needed to
remove direct access to dm timer inside ue_deh and make it to go through
dsp-clock)
