Fix up all sysfs show entries to use sysfs_emit

Signed-off-by: zhangxuezhi1 <zhangxuezhi1@xxxxxxxxxxx>

The patch looks fine apart from the Signed-off-by line. Please use a proper name for the Signed-off-by line. Generally, a romanized version of the forename(s) (given name(s)) followed by the surname (family name) is preferred, for example: Xuezhi Zhang.

Could you please post a "PATCH v2" with a proper Signed-off-by line? Thanks.
