arm64: dts: qcom: qcm2290: Add TCSR download mode address

Browse Source 
Allow configuration of download mode via qcom_scm driver via specifying
download mode register address in the TCSR space. It is especially useful
for a clean watchdog reset without entry into download mode.

The problem remained un-noticed until now since error reporting for
missing download mode configuration feature was explicitly suppressed.
