[PATCH v2] arm64: dts: qcom: hamoa: Add PSCI SYSTEM_RESET2 types

[Xin Liu]

Add support for SYSTEM_RESET2 vendor-specific resets as
reboot-modes in the psci node.  Describe the resets: "bootloader"
will cause device to reboot and stop in the bootloader's fastboot
mode.  "edl" will cause device to reboot into "emergency download
mode", which permits loading images via the Firehose protocol.
