[PATCH][next] powerpc/ps3: replace open-coded sysfs_emit function

[Paulo Miguel Almeida <paulo.miguel.almeida.rodenas@gmail.com>]

sysfs_emit() helper function should be used when formatting the value
to be returned to user space.

This patch replaces open-coded sysfs_emit() in sysfs .show() callbacks
