this patch will be ported uefi. in order to verify other driver,
this patch temporary use it. When uefi replace it, it will delete
it.

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.

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.

This patch adds support for the MHU mailbox peripheral used on Juno by
application processors to communicate with remote SCP handling most of
the CPU/system power management. It also adds the SRAM reserving the
shared memory and SCPI message protocol using that shared memory.

If hardware is already initialised (e.g. by UEFI) then that seems to
cause us problems.

User-side code doing double-buffering expects this in the situations
that ends up using mode_set_base.
Also only set scanout as needed, not on every interrupt, as that isn't
required and is unsafe if the framebuffer state is part way through
being updated.
Code adapted from an earlier version of the driver which was written by
