Add a "reboot-mode" subnode under the psci node in the lemans-evk and qcs6490-rb3gen2 U-Boot device tree overlays, declaring "mode-edl" so that "reset -edl" enters Qualcomm EDL/download mode via a PSCI SYSTEM_RESET2 vendor reset. The magic value <0x80000000 0x00000001> is reset_type = 0x80000000 (vendor bit set) with a cookie of 1.
