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

Add support for SYSTEM_RESET2 vendor-specific resets in
qcm6490-idp 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.
