Add PSCI SYSTEM_RESET2 reboot-modes for qcs615-ride, for use by the
psci-reboot-mode driver.

The following modes are defined:
- bootloader: reboot into fastboot mode for fastboot flashing.
- edl: reboot into emergency download mode for image loading via the
Firehose protocol.

Support for these modes is firmware dependent.
