Add PSCI SYSTEM_RESET2 reboot-modes for qcm6490-idp and qcs6490-rb3gen2 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 and not available across all kodiak based boards.
