mailbox: add Samsung Exynos driver
The Samsung Exynos mailbox controller, used on Google GS101 SoC, has 16
flag bits for hardware interrupt generation and a shared register for
passing mailbox messages. When the controller is used by the
ACPM interface the shared register is ignored and the mailbox controller
acts as a doorbell. The controller just raises the interrupt to APM
after the ACPM interface has written the message to SRAM.
Add support for the Samsung Exynos mailbox controller.
