[PATCH v20 10/10] arm64: dts: qcom: talos: Add psci reboot-modes

[Shivendra Pratap <shivendra.pratap@oss.qualcomm.com>]

Add PSCI SYSTEM_RESET2 reboot-modes for talos based boards, 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.
