Document the new compatible for Hisilicon Hi6220 mailbox driver. Signed-off-by: Leo Yan <leo.yan@linaro.org>

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; enhance rx channel's message queue, which is based on the code in drivers/mailbox/omap-mailbox.c. Now mailbox driver is used to send message to MCU to control dynamic voltage and frequency scaling for CPU, GPU and DDR. Signed-off-by: Leo Yan <leo.yan@linaro.org>

On Hi6220, below memory regions in DDR have specific purpose: 0x05e0,0000 - 0x05ef,ffff: For MCU firmware using at runtime; 0x06df,f000 - 0x06df,ffff: For mailbox message data; 0x0740,f000 - 0x0740,ffff: For MCU firmware's section; 0x3e00,0000 - 0x3fff,ffff: For OP-TEE. This patch reserves these memory regions and add device node for mailbox in dts. Signed-off-by: Leo Yan <leo.yan@linaro.org>

Add sp804 timer for hi6220, so it can be used as broadcast timer. Signed-off-by: Leo Yan <leo.yan@linaro.org>

The previous Kconfig builds Hi6220's common clock driver and stub clock driver together. Stub clock driver has introduced the dependency with CONFIG_MAILBOX, so kernel will not build Hi6220's common clock driver due ARM64's defconfig have not enabled CONFIG_MAILBOX by default. So separately build stub clock driver and common clock driver for Hi6220; and only let stub clock driver has the dependency with CONFIG_MAILBOX. Signed-off-by: Leo Yan <leo.yan@linaro.org>
