commit 28810eecae08f9458a44831978e36f14ed182c80 upstream.
Some msm8996 based devices are unstable when run with VDD_APC of 1.23V, which is listed as the maximum voltage in "Turbo" mode. Given that the CPU cluster is not run in "Turbo" mode, reduce this to 0.98V - the maximum voltage for nominal operation.
