This patch detects presence of SLEEP_SMODE<n>_bm bit definition and
defines set_sleep_mode accordingly, for XMEGA devices. Previously, the
code assumed that all xmegas have 3 bits - this patch removes that
assumption and generalizes it work with devices that have fewer bits.
Committed as rev #2458.
