Changes in v3:
- Split into two patches: one for hamoa, one for purwa
- Move reboot-mode from shared hamoa.dtsi to board-specific files
- Add psci label in hamoa.dtsi to allow board files to reference the node
- Link to v2: https://lore.kernel.org/all/20260226054113.4156874-1-xin.liu@oss.qualcomm.com/

Changes in v2:
- Fix mode-bootloader and mode-edl reset_type
- Link to v1: https://lore.kernel.org/all/20260209042700.1186392-1-xin.liu@oss.qualcomm.com/

[PATCH v3 1/2] 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.
