Subject: [PATCH v3 0/4] arm64: exynos: gs101: add ACPM related nodes

Define SRAM, mailbox and ACPM protocol in device tree.
Enable the mailbox and ACPM protocol in defconfig.

Changes in v3:
- ACPM: don't specify the channel ID and type in DT: the channel ID is
  discovered at runtime and the channel type is always DOORBELL for the
  ACPM interface.
- mbox: update #mbox-cells = <0>;
- rebase on top of v6.13-rc3
- Link to v2: https://lore.kernel.org/r/20241212-b4-acpm-v4-upstream-dts-v2-0-91b7a6f6d0b0@linaro.org

Changes in v2:
- update nodes based on the bindings updates
- update mailbox and power-management (mailbox client) nodes to specify
  channel type (doorbell or data) and channel ID.

v1:
