arm64: dts: qcom: x1e80100: describe tcsr download mode register

Describe the TCSR download mode register to enable download mode
control.

This specifically allows the OS to disable download mode in case the
boot firmware has left it enabled to avoid entering the crash dump mode
after a hypervisor reset by default.
