From: Elliot Berman <elliot.berman@oss.qualcomm.com>

Add support for SYSTEM_RESET2 vendor-specific resets in
qcs6490-rb3gen2 as reboot-modes. Describe the 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.
