ARM: dts: msm: Add pin setup for modem-QSPI mux on 8996

Browse source 
Auto platforms have an external mux that needs to be setup
to choose between QSPI and modem. Prior to the modem being
loaded, the mux needs to be setup for modem to use the pin.
This is a one time configuration at bootup, that is performed
by pil driver.
