Add PSCI SYSTEM_RESET2 reboot-modes for lemans-evk and lemans-ride-common(sa8775p-ride, sa8775p-ride-r3, qcs9100-ride, qcs9100-ride-r3) 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.
