ARM: DTS: msm: Enable Sign Of Life(SOL) for Sun + Peach

Browse Source 
SOL is side band mechanism to communicate with device
and reset device from the bad state. Enable SOL for
sun  to recover from device hung issue during PCIe link
down cases.

HOST_SOL -------> Host to Device GPIO
DEV_SOL --------> Device to Host GPIO
