Convert the hisilicon,hi6220-mbox binding to DT schema format. It's a
straight forward conversion.

-Hisilicon Hi6220 Mailbox Driver
-===============================
-
-Hisilicon Hi6220 mailbox supports up to 32 channels. Each channel
-is unidirectional with a maximum message size of 8 words. I/O is
-performed using register access (there is no DMA) and the cell
-raises an interrupt when messages are received.
-
-Mailbox Device Node:
-====================
-
-Required properties:
---------------------
-- compatible: Shall be "hisilicon,hi6220-mbox"
-- reg: Contains the mailbox register address range (base
- address and length); the first item is for IPC
- registers, the second item is shared buffer for
- slots.
-- #mbox-cells: Common mailbox binding property to identify the number
- of cells required for the mailbox specifier. Must be 3.
- <&phandle slot_id dst_irq ack_irq>
- phandle: Label name of mailbox controller
- slot_id: Slot id used either for TX or RX
- dst_irq: IRQ identifier index number which used by MCU
- ack_irq: IRQ identifier index number with generating a
- TX/RX interrupt to application processor,
- mailbox driver uses it to acknowledge interrupt
-- interrupts: Contains the interrupt information for the mailbox
- device. The format is dependent on which interrupt
- controller the SoCs use.
-
-Optional Properties:
---------------------
-- hi6220,mbox-tx-noirq: Property of MCU firmware's feature, so mailbox driver
- use this flag to ask MCU to enable "automatic idle
- flag" mode or IRQ generated mode to acknowledge a TX
- completion.
-
-Example:
---------
-
- mailbox: mailbox@f7510000 {
- compatible = "hisilicon,hi6220-mbox";
- reg = <0x0 0xf7510000 0x0 0x1000>, /* IPC_S */
- <0x0 0x06dff800 0x0 0x0800>; /* Mailbox */
- interrupt-parent = <&gic>;
- interrupts = <GIC_SPI 94 IRQ_TYPE_LEVEL_HIGH>;
- #mbox-cells = <3>;
- };
-
-
-Mailbox client
-===============
-
-Required properties:
---------------------
-- compatible: Many (See the client docs).
-- mboxes: Standard property to specify a Mailbox
- Cells must match 'mbox-cells' (See Mailbox Device Node above).
-
-Optional Properties:
---------------------
-- mbox-names: Name given to channels seen in the 'mboxes' property.
-
-Example:
---------
-
- stub_clock: stub_clock {
- compatible = "hisilicon,hi6220-stub-clk";
- hisilicon,hi6220-clk-sram = <&sram>;
- #clock-cells = <1>;
- mbox-names = "mbox-tx", "mbox-rx";
- mboxes = <&mailbox 1 0 11>, <&mailbox 0 1 10>;
- };
