mailbox: Hi6220: add mailbox driver
Add driver for Hi6220 mailbox, the mailbox communicates with MCU; for sending data, it can support two methods for low level implementation: one is to use interrupt as acknowledge, another is automatic mode which without any acknowledge. These two methods have been supported in the driver. For receiving data, it will depend on the interrupt to notify the channel has incoming message. Now mailbox driver is used to send message to MCU to control dynamic voltage and frequency scaling for CPU, GPU and DDR.
