Subject: [PATCH] ARM: dts: msm: Update GPU thermal rule for lahaina

GPU thermal mitigation configuration uses a virtual sensor, which will
estimate the max of two GPU sensors. Change the GPU thermal rule to
directly use these individual sensors in two separate rule to achieve a
better thermal control.
