[PATCH v27 07/10] arm64: dts: qcom: Add psci reboot-modes for kodiak boards

[Shivendra Pratap]

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.
