Subject: [PATCH v3 01/14] clk: qcom: gcc: fix sm8150 GPU and NPU clocks

Fix the parents and set BRANCH_HALT_SKIP. From the downstream driver it
should be a 500us delay and not skip, however this matches what was done
for other clocks that had 500us delay in downstream.

Fixes: f73a4230d5bb ("clk: qcom: gcc: Add GPU and NPU clocks for SM8150")
