[DPU PATCH v2 11/14] drm/msm/dpu: remove topology name

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

From: Jeykumar Sankaran <jsanka@codeaurora.org>

Strip down the support for topology enums. It
can be replaced with simple hw count checks.

changes in v2:
     - none
