staging: greybus: arche: use sysfs_emit() instead of sprintf()

Replace sprintf() with sysfs_emit() in state_show() sysfs attribute
callbacks in arche-platform.c and arche-apb-ctrl.c.

Checkpatch complains about code using sprintf(). This code here is
obviously safe as-is, but it would be more appropriate to use
sysfs_emit().
