mailbox: rockchip: Add Rockchip mailbox driver
This driver is found on RK3368 SoCs. The Mailbox module is a simple APB peripheral that allows both the Cortex-A53 MCU system to communicate by writing operation to generate interrupt. The registers are accessible by both CPU via APB interface. The Mailbox has the following main features: 1) Support dual-core system: Cortex-A53 and MCU. 2) Support APB interface. 3) Support four mailbox elements, each element includes one data word, one command word register and one flag bit that can represent one interrupt. 4) Four interrupts to Cortex-A53. 5) Four interrupts to MCU. 6) Provide 32 lock registers for software to use to indicate whether mailbox is occupied.
