[PATCH v3 0/4] Add SRAM Nodes for VPU

Hello All,

This series is responsible for adding the SRAM nodes for the Wave5 VPU to
use. First patch is responsible for carving out the SRAM pool from
main_navss that the VPU on J721s2 will then reference.

The last 2 patches use the existing oc_sram pool already found in the
relevant device trees.


Changes since v2:

  - Removed j784s4 since there are two vpu instances, need to find
    another SRAM pool so both can get full benefit of B/W savings

Changes since v1:

  - properly updates the nodename in the first two patches to pass
    dtbs_check. 

Best,
Brandon
