arm64: dts: exynos: gs101: add AP to APM mailbox node

Browse source

GS101 has 14 mailbox controllers. Add the AP to APM mailbox node.

Mailbox controllers have a shared register that can be used for passing
the mailbox messages. The AP to APM mailbox controller is used just as a
doorbell mechanism. It raises interrupt to the firmware after the mailbox
message has been written to SRAM where the TX/RX rings are defined.
