[PATCH] iio: bma180: Convert to use sysfs_emit_at() API

[<ye.xingchen@zte.com.cn>]

From: ye xingchen <ye.xingchen@zte.com.cn>

Follow the advice of the Documentation/filesystems/sysfs.rst and show()
should only use sysfs_emit() or sysfs_emit_at() when formatting the
value to be returned to user space.
