Hi3660 mailbox controller is used to send message within multiple
processors, MCU, HIFI, etc. This patch series is to implement an
initial version for Hi3660 mailbox driver with "automatic
acknowledge" mode.
The patch set have been verified with Hi3660 stub clock driver, so
we can send message to MCU to execute CPU frequency scaling. This is
tested on 96boards Hikey960.
Changes from v2:
* According to Mark Rutland suggestions, removed sev()/wfe() from
driver, the system has no two masters sharing the same channel for
data transferring so we don't need these instructions;
* Refined DT binding and doc according to Rob suggestions;
* Refined driver according to Julien suggestions;
Changes from v1:
* Added cover letter to track the changelog;
* Added document for DT binding;
* Refactored and simplized mailbox driver with "automatic ack" mode;
* Refined commit logs for patches;
