Subject: [PATCH] drm/imagination: Optionally depend on POWER_SEQUENCING

When the change using pwrseq was added, I nixed the dependency on
POWER_SEQUENCING since we didn't want it pulled in on platforms where
it's not needed [1]. I hadn't, however, considered the link-time
implications of this for configs with POWER_SEQUENCING=m.

Fixes: e38e8391f30b ("drm/imagination: Use pwrseq for TH1520 GPU power management")
Cc: stable@...r.kernel.org
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202510111806.CMulNMKW-lkp@intel.com/
