[PATCH v2 4/4] arm64: dts: qcom: Add PSCI SYSTEM_RESET2 types for qcm6490-idp

Add nodes for the vendor-defined system resets. "bootloader" will cause
device to reboot and stop in the bootloader's fastboot mode. "edl" will
cause device to reboot into "emergency download mode", which permits
loading images via the Firehose protocol.
