ARM: dts: msm: Do not initialize the reset line for sda845+sdx24

In the event of the modem error fatal, it excepts the APQ to hold
the reset line as it is during its bootup. Initializing this to
LOW would trigger a cold reset on the modem. As a result, the
modem is powered-off, and the ramdumps are lost. Avoiding
initializing the reset gpio to LOW would hold the modem up
(unchanged) and the ramdumps are available.
