Add a devicetree binding for the Axiado AX3005 mailbox controller.
The controller provides inter-processor communication channels
between the host CPU and the coprocessor, with separate TX and RX
register regions.

Add the corresponding MAINTAINERS entry covering the binding.

Add the APCS mailbox compatible for the IPQ5210 SoC. It uses the IPQ6018
APCS mailbox compatible as a fallback, so document the valid compatible
string combination in the binding.

Document support for a mailbox present on Exynos850-based platforms.
The registers offsets are different from gs101 mailbox, but the
workflow is similar, hence new compatible.
