[DPU PATCH v2 02/14] drm/msm/dpu: remove resource pool manager

[Sravanthi Kollukuduru <skolluku-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>]

From: Jeykumar Sankaran <jsanka@codeaurora.org>

resource pool manager utility was introduced to manage
rotator sessions. Removing the support as the rotator
feature doesn't exist.

changes in v2:
     - none
