From: Brian Masney <masneyb@onstation.org>

Add support for the a3xx GPU. opp_table is chosen to include lower
frequencies common to all different msm8974 variants.

Also correctly set gpu compat string on msm8974 and msm8974pro.

- put opp_table node inside gpu node (similar to msm8916)
- fix tabs-whenever-possible lint warning

v2: https://lkml.org/lkml/2021/1/24/142
