From: Kevin Wangtao <kevin.wangtao@linaro.org>


As the next patches will provide support for the hikey3660's sensor,
several functions with the same purpose but for different platforms will
be introduced.

In order to make a clear distinction between them, let's prefix the
function names with the platform name.

This patch has no functional changes, only name changes.
