ARM: dts: msm: Update GPU, core isolation and hotplug threshold for SHIMA

Update core isolation and hotplug threshold for silver CPUs to 110C
and 112C. Update core isolation and hotplug threshold for gold and
gold plus to 108C and 110C.

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.
