Current mailbox driver of Hi3660 release the mailbox directly before sending a new message which may cause last message lost and next message sending doesn't take effect actually. This patch fixs this issue by following the right progress below, each time before sending a message, mailbox driver will check whether the mailbox is in ready state, if last message has been acknowledged, the mailbox driver will clear the ack state to turn the mailbox to ready state again.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
