sa8775p-ride firmware supports vendor-defined SYSTEM_RESET2 types.
Describe the reset types: "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.
