dt-bindings: firmware: qcom,scm: support indicating SDI default state 



IPQ5018 has SDI (Secure Debug Image) enabled by TZ by default, and that
means that WDT being asserted or just trying to reboot will hang the board
in the debug mode and only pulling the power and repowering will help.
Some IPQ4019 boards like Google WiFI have it enabled as well.

So, lets add a boolean property to indicate that SDI is enabled by default
and thus needs to be disabled by the kernel.
